AB  - Sustainable solutions for environmental remediation are of great interest due to the escalated release of toxic substances into the ecosystem. Here, Ca-impregnated pyro-hydrocarbon (Ca-SMS) was synthesized from spent mushroom substrate (SMS) via hydrothermal carbonization at a relatively low process temperature, followed by subsequent physicochemical activation. Ca-SMS underwent characterization using various analytical techniques, and its efficacy in removing acridine red (AR) and methylene blue (MB) was assessed through batch experiments. The results suggested that Ca-SMS is an effective adsorbent for AR and MB, visiting a removal capacity of 33.82 and 81.98 mg g 1 at 35 ◦ C, respectively. The kinetic investigation uncovered that the dye removal process mostly agreed with the pseudo-second-order (PSO), while the Langmuir and Freundlich models were the most suitable to describe the removal of dyes. Thermodynamic analyses showed that the remediation process is spontaneous and endothermic. Adsorption mechanisms among dyes and Ca-SMS were multiple: physical adsorption, surface complexation, electrostatic, and ππ interaction. The feasibility of the proposed method for real sample treatment was demonstrated. These findings indicate that Ca-SMS is an effective alternative sorbent for the remediation of textile wastewater and is a viable solution for waste reduction in the rising mushroom cultivation sector.

AB  - Irradiated fig pomace pyrochar (IrrPyrFP) is noteworthy as a novel sterilized low-cost sorbent of BTEX, pesticides, and Pb2+ ions. It was produced by applying pyrolysis treatment followed by gamma irradiation modification in order to obtain a highly efficient and sterile sorbent. The characterization of fig pomace before and after pyrolysis, as well as before and after irradiation of the obtained pyrochar, was done using SEM, FTIR, and elemental analysis, while its sorption ability was tested through the removal of examined pollutants by batch sorption experiments. The obtained results suggest that IrrPyrFP could play a significant role in the control of environmental pollutants, as indicated by the maximum adsorption capacities: 42 mg g−1 for BTEX, 0.625 mg g−1 for malathion, 0.495 mg g−1 for chlorpyrifos and 255 mg g−1 for Pb2+. A kinetic study showed that the removal process by IrrPyrFP mainly follows pseudo 2nd kinetics order, while the sorption equilibriums were estimated using the Langmuir and Freundlich model. Overall, the findings of this work suggest that pyrolysis and activation by irradiation of waste biomass is a promising way to produce sterile efficient sorbents for waste-water treatment based on green chemistry. Additionally, the demonstrated application of fig pomace promotes the potential of using this biomass for continual and economical waste management in the rising fig industry.

AB  - In this research, a composite based on montmorillonite (K10) modified with HDTMABr was used. The characterization of the pure K10, NaMMT and OMMT was performed using XRD, FTIR-ATR, SEM, TG, DTG, and DTA. Ion exchange capacity (CEC) and specific surface area (SSA) were also determined. The sulfite method was used to determine free and liberated formaldehyde (FA) from synthesized urea-formaldehyde/montmorillonite (UF/ MMT) composites. This research aims to demonstrate the bifunctionality of OMMT and that it can be used both for the capture of FA from the synthesized cross-linked UF resin and for the adsorption of the anionic dye Acid Red 183 (AR183) from aquatic medium. SEM analysis showed that there are changes in the morphology of the OMMT and the formation of a hollow network, which affects the absorption capacity of the clay. The calculated values of free and liberated FA in the UF/OMMT composites are drastically reduced and amount to 0.12% and 0.96%, respectively, compared to the composites with K10 (0.6% and 2.04%, respectively). Also, very promising results were obtained of the adsorption of AR183 dyes from the aquatic medium using OMMT. The results show that OMMT (0.5 g OMMT/50 cm3 aqueous dye solution, c=20 mgdm− 3 ) managed to remove 85.95% of AR183 dye (pH dye=7). The adsorption mechanism of AR183 on OMMT follows the Freundlich isotherm and proceeds according to the pseudo-first-order kinetic model. Overall, the findings of this work indicate that the use of the obtained OMMT has great potential in removing pollutants from two totally different systems.

AB  - The removal of environmental pollutants is significant because of their harmful effects on living organisms. Biochar is favorable as a natural adsorbent of environmental pollutants due to its advantages, such as environmental acceptability and economic profitability. This study evaluated the potential of pyrolyzed plum pomace (PyrPP) as an adsorbent for environmental pollutants: Pb2+ ions, pesticides (chlorpyrifos and malathion), as well as organic pollutants BTEX. In order to ameliorate the adsorption capacity of PyrPP, modification by gamma irradiation was performed. Irradiated plum pomace biochar (IrPyrPP) has been shown to be an effective adsorbent, and the material is also sterilized by irradiation, which makes this material potentially sterile adsorbents of the most environmental pollutants from water. The irradiated biochar showed better adsorption performances for the removal of Pb2+ ions, BTEX, and chlorpyrifos. Maximum adsorption capacity (Qmax) of PyrPP for Pb2+, BTEX, chlorpyrifos, and malathion adsorption was 157.0, 17.6, 0.219, and 1.067 mg g− 1 , while Qmax of IrPyrPP for Pb2+, BTEX, chlorpyrifos and malathion was 271.0, 48.0, 0.428 and 0.593 mg g− 1 , respectively. The results obtained during this research suggest that biomass pyrolysis and modification of this biomass by irradiation is a promising way to produce efficient natural sterile sorbents for wastewater treatment.

AB  - Liqueur from green walnuts is one of the many traditional medicines in folk medicine. It owes its healing properties to the main ingredient - unripe green walnuts. Green walnuts are a natural reservoir of vitamin C, vitamin B complex, vitamin E, calcium, potassium, magnesium, phosphorus, iron, zinc and iodine. Liqueur made from green walnuts is mostly used for problems with the thyroid gland, anemia, and various stomach infections. The liqueur is made by adding green walnuts to a container with sugar or honey and brandy, and leaving them to be exposed to the sun's rays for a period of 40 days. Photons accelerate the release of medicinal substances from green walnuts. This period of exposure is quite long, the quality of the liqueur is affected by the amount of solar energy delivered during that period, and contamination may occur during manual handling. All these problems can be solved by using photons from a radioactive gamma source instead of photons from the sun. The paper describes the process of obtaining liqueur from green walnuts using gamma radiation, as well as the comparison of the composition of liqueur obtained in the traditional way, with the effect of sunlight, and the application of an innovative method using gamma rays.

AB  - Mushroom cultivation and consumption have been steadily increasing in recent decades, however, after mushroom cultivation, a large amount of by-products, known as spent mushroom substrate (SMS), are left behind in open dumps where about 5 kg of SMS are generated for every kilogram of mushroom (Agaricus bisporus). Around 51 million tons of SMS are produced in the world every year. Hydrothermal carbonization (HTC) is a promising technology for the conversion of SMS into a rich carbon product, hydrochar. The hydrochar was synthesized in a hydrothermal reactor at a temperature of 180 °C for a reaction time of 1 h. The characterization of the SMS and its chars was done by FTIR, SEM, and TGA analysis. The FTIR analysis showed that aromatic and oxygen-rich functional groups are dominant on the hydrochar surface. It was noticed that the hydrochar had more visible pores compared to the SMS. The porous structure and oxygen functional groups of hydrochar probably influenced the improvement of adsorption performance, since the adsorption capacity of SMS for Cd2+ ions was 28 mg L-1, while for hydrochar it was 92 mg L-1. On the other hand, the thermal kinetic analysis has shown that hydrothermally treatment upgrades the combustion behavior of hydrochar. The kinetic parameters were determined by Kissinger and Ozawa methods. The hydrochar had notably lower activation energy compared to the SMS, which means that this hydrochar requires a smaller amount of energy to start combustion. The preliminary results show that HTC effectively transforms SMS into alternative solid biofuel and eco-friendly sorbent.

AB  - In this work, betaine (trimethyl glycine) and tannin (complex biomolecules of polyphenolic nature) were used as bio-fillers. Urea-formaldehyde (UF) resin with a molar ratio of formaldehyde versus urea (FA/U) of 0.8 was synthesized in situ with tannin and betaine as bio-fillers, to obtain UF resin with reduced free FA content and increased hydrolytic and thermal stability by the principles of sustainability. The samples TUF (with tannin) and BUF (with betaine) were characterized by using X-ray diffraction analysis (XRD), non-isothermal thermogravimetric analysis (TGA), and differential thermal analysis (DTA), supported by data from Fourier Transform Infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). The percentage of free FA in modified BUF resin is 0.1%, while the percentage of free FA in tannin-modified resin is 0.8%. The hydrolytic stability of the modified UF resins was determined by measuring the concentration of liberated FA in the modified UF resins, after acid hydrolysis. The modified BUF resin is hydrolytically more stable because the content of released FA is 3.6% compared to the modified TUF resin, where it was 7.4%. Based on the value for T5%, the more thermally stable resin is the modified TUF resin (T5% = 123.1°C), while the value of the T5% for the BUF resin is 83.1°C. This work showed how UF bio-composite with reduced free FA content and increased hydrolytic and thermal stability can be obtained using tannin and betaine as bio-fillers.

AB  - In this paper, the synthesis of modified urea-formaldehyde (UF) composites with differently activated montmorillonite KSF (UF/KSF) was performed. Two types of montmorillonite (MMT) KSF were used: sample activated with sulfuric acid-KSF(H2SO4) and sample activated with acid and stirring-KSF(H2SO4+stirrer). In order to examine the effect of KSF activation mode on the thermal and hydrolytic stability of UF resins, thermogravimetric analysis (TGA) was performed, as well as A determination of the amount of liberated formaldehyde (FA) after acid hydrolysis. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis were used to characterize the samples of modified UF/KSF composites and differently activated KSF. Activation of KSF led to a decrease in its specific surface area (SSA) and to an increase in cation exchange capacity (CEC). SEM analysis showed that in the KSF(H2SO4+stirrer) sample, the layered microstructure was disrupted. Free formaldehyde was not detected in the sample of UF resin with KSF(H2SO4), and in the sample with KSF(H2SO4+stirrer) it was 0.06%. The UF/KSF(H2SO4) composite showed higher hydrolytic stability (3.9%) compared to UF/KSF(H2SO4+stirrer) (4.62%), but lower compared to the UF/KSF(inactive) (1.23%). TG analysis showed that the KSF(H2SO4) sample had better thermal stability than the KSF(H2SO4+stirrer) sample, but this did not contribute to the better thermal stability of UF/KSF(H2SO4) compared to UF/KSF(H2SO4+stirrer), both samples had a T5% value of 112 °C.

AB  - To provide new insight into the field of urea-formaldehyde (UF) adhesives science, in this work, for the first time, UF resin was modified with hydrochar of spent mushroom substrate (HCUF) and chitosan (CHUF) to investigate the effect of these bio-fillers on the hydrolytic and thermal stability of in situ prepared UF resins. The characterization of the modified UF biocomposites was performed using X-ray diffraction analysis (XRD), Fourier transforms infrared spectroscopy (FTIR), non-isothermal thermogravimetric analysis (TG), differential thermal gravimetry (DTG), and differential thermal analysis (DTA). Scanning electron micrographs (SEM) of the CHUF and HCUF biocomposites show a spherical structure that differs from each other because the surface of the CHUF biocomposite has pronounced pores that form a network structure. With its hydroxyl and amino groups, chitosan bonding to UF resin through hydrogen bonds, which is confirmed by FTIR analysis. The content of free FA in CHUF biocomposite is 0.06%, while that of HCUF is higher and amounts to 0.48%. The content of released FA in both modified UF biocomposites was similar (2.5% and 2.8% for CHUF and HCUF, respectively). The hydrolytic stability of CHUF is slightly higher compared to the HCUF biocomposite. Thermal analysis shows that the CHUF is thermally more stable because it starts to decompose at a slightly higher temperature than the HCUF biocomposite.

AB  - Lanthanide-doped apatite biomaterials are highly promising in medicine because of their excellent chemical and optical properties. In this study, Eu(III)-doped fluorapatite particles have been successfully synthesized by a wet method at room temperature. The characterization study from XRD showed that obtained powder is monophasic fluorapatite. Biomaterials based on fluorapatite (Ca10(PO4)5F2) doped with lanthanide elements are ideal contrast agents for a variety of biomedical applications, e.g. detection, imaging, cell tracking, and therapy [1]. Eu(III) received a great deal of interest because of several desirable properties like emission in the visible region, long luminescent lifetime, and less sensitivity to quenching by singlet oxygen [2].

AB  - Urea-formaldehyde (UF) resins are the leading adhesive in the wood industry. Their disadvantages are low water resistance and formaldehyde (FA) emissions from wood panels due to the low stability of the amino-methylene bond. Since FA has a detrimental effect on the environment and human health, the main goal of the modern adhesives industry is to produce efficient UF adhesives with low amounts of emitted, if not without, FA. One way to achieve this is to add a formaldehyde scavenger. In this work, UF resins modified with zeolite type ZSM-5 and bentonite as free FA scavengers are analyzed and compared. A total of three UF resins were synthesized: pure UF resin (UF), UF composite containing zeolite (ZUF), and bentonite (BUF) under the same conditions. Specific surface area (SSA) and cation exchange capacity (CEC) for bentonite and zeolite were determined. SSA (Sears' method) for bentonite is 19.9 m2/g and for zeolite 39.1 m2/g. The CEC of bentonite is 0.68 mol/kg, and that of zeolite is 0.1 mol/kg. The disulfide method was used to determine free FA in modified UF resins. The amount of free FA in the ZUF composite is 0.06%, while in the BUF composite is 0.18%. The hydrolytic stability of modified UF resins was determined by measuring the amount of liberated FA in the modified UF resins after acid hydrolysis. The results show that the amount of released FA in the ZUF composite is 4.08%, while in the BUF resin, it is 4.8%. Based on the obtained results, it can be concluded that zeolite is a better scavenger of free FA than bentonite and that its ZUF composite is hydrolytically more stable than the BUF composite.

AB  - Phase change materials (PCM) are attractive energy storage technologies due to their high energy storage density and the ability to reversible absorb and release thermal energy at a nearly constant temperature. Polymers and polymer-based eutectic mixtures are promising PCMs. This study aims to investigate heat properties (melting temperature (Tm), latent heat (ΔH) and thermal conductivity(λ)) of potential PCMs based on polyethylene glycol polymer (PEG2000). We prepared following two and three components materials: PEG2000: ethylene glycol (5:6): PEG2000: PPG 400 (1:5); PEG2000: PPG400: Choline chloride (2:2:15); PEG2000: ethylene glycol (5:6); PEG2000: Glyoxal (5:2). The prepared three components material belong to deep eutectic solvents. Tm of the prepared materials are lower compared to pure PEG2000 (Tm = 57 ºC) e.g. Tm of PEG2000: PPG400: Choline chloride is 43 ºC. The determined melting enthalpies are also lower for prepared materials compared to PEG2000. This decrease is lower for eutectic mixture such as PEG2000: Choline chloride: ethylene glycol. We can conclude based on the obtained result that eutectic mixtures based on polymers are promising PCMs.

AB  - A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2·5H2O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC’s sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g−1, and 131 mg g−1, respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudo-second kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation–π interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

AB  - In this study, zinc phthalocyanine was evaluated as a possible chemical dosimeter for gamma rays at low-medium dose ranges in solution form and PVA film. The zinc phthalocyanine was successfully synthesized with a high yield under microwave irradiation at 200 °C. The calibration curves of absorbance versus dose of gamma irradiation show excellent linearity over a wider dose range (1 - 25kGy). After being irradiated, the samples' color changed from blue to yellow.

AB  - In this study, the thermal and hydrolytic properties of composite systems based on the urea–formaldehyde resin (UF) and eco-friendly montmorillonite (K10) as formaldehyde (FA) scavenger were examined. UF resin with molar ratio FA:U = 0.8 was synthesized in situ with inactivated, and activated K10. K10 was activated by sulfuric acid (H2SO4) with and without magnetic stirring. The samples are marked with $${\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4}\right)}$$,$${\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$, $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}$$, and $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$, respectively. X-ray diffraction analysis and non-isothermal thermogravimetric analysis, supported by data from Fourier transform infrared spectroscopy and scanning electron microscopy were used to characterize the samples. Based on the measurement of specific surface area (SSA), the degree of activation was determined. Measurement of the SSA shows that higher values were obtained for modified K10 compared to inactive K10. The amount of free and liberated FA was 0.06% and 4.6% for $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}$$and 0.12% and 4% for $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$. This research showed that the $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}$$composite has a lesser amount of free FA (0.06%) in comparison to the $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$composite (0.12%). The $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$composite has a higher resistance to acidic hydrolysis. The modified $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4}\right)}$$composite is more thermally stable than $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$composite.

AB  - Redirecting waste biomass back into the economy can reduce their burden on the environment. The use of waste biomass for the production of fuels, value-added materials or natural fillers has significant economic and environmental benefits. Physico-chemical characterization of waste biomass (plum pomace and fig pomace) was done by proximate, elemental, biochemical analysis, FTIR and SEM analysis. The calorific value of both biomasses can be compared with the calorific value of lignite, which rises their potential use as a solid biofuel. The combustion behavior of biomass was investigated by thermal analysis techniques. Based on thermal degradation experiments performed at four heating rates a kinetic analysis of the biomass decomposition process was accomplished. The kinetic study was done using Kissinger method, Ozawa method, Flynn-Wall-Ozawa (FWO) method, Starink method, and Kissinger-Akahira-Sunose (KAS) method. The value of activation energy obtained by different kinetic methods was ∼210 kJ/mol for plum pomace and ∼162 kJ/mol for fig pomace. Estimated activation energy values were used to calculate thermodynamic parameters. In addition to the fact that the obtained results can serve as a useful reference for the design of pyrolysis reactors, this research has ecological significance because it solves the problem of solid waste disposal.

Biochar produced by pyrolysis of fig pomace at 500 °C were characterized and investigated as adsorbents for the removal of Pb2+ ions from aqueous solution. Fig pomace before and after pyrolysis was characterized using proximate, inorganic and elemental analysis, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Biochar has a carbon matrix with a high degree of porosity and large surface area, suggesting that it can be used as a surface adsorbent and thus have a significant role in controlling environmental contaminants. The surface modification by gamma irradiation was done to enhance the adsorption capacity of biochar. The Pb2+ ions contents in aqueous solution were analyzed using ICP-OES. The adsorption capacity was estimated using the Freundlich and Langmuir model. The results of this work suggest that pyrolysis and irradiation of biomass is a promising way to produce efficient heavy metal sorbents for waste-water treatment.

AB  - The use of waste biomass for the production of fuels, sorbent of different pollutants or natural fillers has significant economic and environmental benefits. Plum (Prunus domestica) is a lush fruit consisting of bones, flesh and skin. It can be consumed fresh, dried or used to make juices, jams and brandies known as plum brandy. Plum is also known as a laxative. During processing, plum pomace is formed as a by-product of plum brandy production. Plum pomace contains a large proportion of polyphenols, so it can be used to produce dietary supplements. Therefore, in this study, the gamma irradiation activated biochar of plum pomace was examined as a lowcost biosorbent of Cd2+ ions from aqueous solution. It was prepared using pyrolysis process at 500 °C for a reaction time of 1 h, then was activated by gamma irradiation. The characterization of plum pomace before and after pyrolysis was done by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Analysis of morphology and functional groups presented the formation of cracks on the biochar surface, which are mainly dominated by oxygen-rich functional groups. The adsorption capacity of activated biochar was higher than inactivated biochar because its improved surface functional properties after gamma activation. The Cd2+ ions contents in aqueous solution were analyzed using ICP-OES. The adsorption capacity was estimated using the Langmuir and Freundlich model. The findings of this study confirm that pyrolysis is a promising way to produce efficient environmentally friendly sorbents for wastewater treatment.

AB  - In this study, the adsorption capacity of Pb2+ removal from aqueous solution was examined by hydrochar of the spent mushroom substrate. In order to improve the adsorption capacity, hydrochar was previously activated with 2M KOH. The obtained results demonstrated that alkally activation increased the sorption capacity from 36 mg g-1 to 74 mg g-1. Structural characterization of activated and inactivated hydrochars were performed by FTIR analysis. Toward to obtained results of FTIR analysis, the increased of the oxygen functional groups (OFG) in activated hydrochars was perceived, which is contributed to the increase in the adsorption capacity of this carbonized material. Results indicated that spent mushroom substrate can be converted into hydrochar as a perspective sorbent for removal of Pb2+.

AB  - Two new cationic Cu(II) complexes of cyclam (1,4,8,11-tetraazacyclotetradecane) and aminocarboxylate coligands glycine or alanine have been synthesized. The complexes were characterized by elemental analysis (C, H and N), molar electrical conductivity, magnetic susceptibility measurement at room temperature, spectral methods (UV/Vis and Fourier transform infrared), as well as by thermogravimetric (TG) and differential thermal analysis (DTA). The analytical data of the complexes show the formation of mononuclear complexes with general formula [Cu(L)cyc](ClO4)2·nH2O, A) L = glycine, n = 1.5 and B) L = alanine, n = 2.5. The tetradentate ligand cyclam was coordinated to metals through four N donors. The spectroscopic data suggested that the amino carboxylate ligands coordinated via their carboxylate ion moieties. The six- -coordinate octahedral geometry around Cu(II) in both complexes was presumed. TG-DTA analysis indicated that complex B decomposed exothermally in a single step in the range of 310–400°C. The cytotoxic activity of Cu(II) complexes and the starting ligands were tested against human cervix adenocarcinoma cell line (HeLa), human melanoma (FemX) and human colon carcinoma (LS174). The IC50 values for the Cu(II) complexes were from 48.35–82.25 μM. Both complexes were tested for their antimicrobial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and the yeast Candida albicans.

Biochar has a carbon matrix with a high degree of porosity and large surface area, suggesting that it can be used as a surface adsorbent and thus have a significant role in controlling environmental contaminants. The surface modification by gamma irradiation was done to enhance the adsorption capacity of biochar. The Pb2+ ions contents in aqueous solution were analyzed using ICP-OES. The adsorption capacity was estimated using the Freundlich and Langmuir model. The results of this work suggest that pyrolysis and irradiation of biomass is a promising way to produce efficient heavy metal sorbents for waste-water treatment.",

AB  - The aim of this study was to investigate thermal behavior of the new complex with formula [Cu(ala)cyc](ClO4)2∙2.5H2O. The complex was isolated and previously characterized by: elemental analysis (C, H, N), molar conductivity, UV/Vis and FTIR spectroscopy and magnetic measurements at room temperature. The sixcoordinate octahedral geometry around Cu(II) complexes was proposed. The experimental data suggested that the tetradentate ligand cyclam was coordinated to metals through four N donors and the amino carboxylate ligand coordinated via carboxylate ion. Investigate of thermal stability can be crucial in confirming the structure as well as in assessing the applicability of new compounds. The thermal properties of these complex have been investigated by thermogravimetric (TG) and differential thermal analysis (DTA). Therefore, TG-DTA analysis indicates that investigated complex decomposes exothermally in a single step in the range of 310 - 400 °C.

AB  - The effect of different montmorillonites (KSF and K10) and their modifications (Na-KSF, Na-K10) on content of formaldehyde-FA (free and liberated) modified urea-formaldehyde (UF) composites was investigated. KSF and K10 were modified by sodium chloride (NaCl). A total of four samples were synthesized, with the designations UF/KSF, UF/Na-KSF, UF/K10, and UF/Na-K10, under the same conditions. The content of free FA was determined by the bisulfite method. The hydrolytic stability of modified UF resin was determined by measuring the concentration of liberated FA of modified UF composites after acid hydrolysis. The specific surface area of the tested montmorillonites was determined by the Sear's method. Higher values of specific surface area were obtained for pure KSF (149.4 m2/g) compared to modified Na-KSF (48.6 m2/g). Specific surface area for pure K10 was 111 m 2/g, compared to value of 71 m2/g for modified Na-K10. The amount of free and liberated FA was 0.4%, 0.12% and 1.2% and 2.3%, respectively for UF/KSF and UF/Na-KSF composite. The values for free FA for UF/K10 and UF/Na-K10 composite are the same and amount to 0.6%. It was concluded that the UF/Na-KSF composite has a smaller content of free FA (0.12%) compared to other UF composites. The UF/KSF composite has a higher resistance to acidic hydrolysis and lower liberated FA percent (1.2%).
