AB  - In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to those achieved within classical syntheses. In order to optimize the continuous flow syntheses and increase the yield of the products, the retention time in the microreactor was varied by changing the flow rates of the reactant solutions. Furthermore, the reaction was optimized for 3-cyano-4,6-dimethyl-2-pyridone and 3-cyano-6-hydroxy-4-methyl-2-pyridone, which are comercially important in the pharmaceutical and dye industries. Both 2-pyridones were obtained in satisfactory yield of circa 60 % in less than 10 min. The resulting compounds were characterized by their melting points, FT-IR, H-1-NMR and UV-Vis spectra. The efficiency of the presented method for the synthesis of 2-pyridone-based molecules has promising potential for industrial production.

AB  - The modification of the fly ash (FA) by magnetite (M) was performed to obtain FAM adsorbent with improved adsorption efficiency for arsenate removal from water. The novel low cost adsorbents are characterized by liquid nitrogen porosimetry (BET), scanning electron microscopy (SEM), X-ray diffraction (XRD), Mössbauer spectroscopy (MB) and Fourier transform infrared (FTIR) spectroscopy. The optimal conditions and key factors influencing the adsorbent synthesis are assessed using the response surface method (RSM). The adsorption experiment was carried out in a batch system by varying the contact time, temperature, pH, and mass of the adsorbent. The adsorption capacity of the FAM adsorbent for As(V), calculated by Langmuir model, was 19.14 mg g−1. The thermodynamic parameters showed spontaneity of adsorption with low endothermic character. The kinetic data followed the pseudo-second-order kinetic model (PSO), and Weber-Morris model indicated intra-particle diffusion as rate limiting step. Alternative to low desorption capability of the FAM was found by five consecutive adsorption/magnetite precipitation processes which gave exhausted layered adsorbent with 65.78 mg g−1 capacity. This research also has shed light on the mechanism of As(V)-ion adsorption, presenting a promising solution for the valorization of a widely abundant industrial waste. © 2018 Elsevier Ltd

AB  - This study focuses on the use of raw fly ash (FA) and modified fly ash – activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+and As(V)), followed by the revalorization of the exhausted adsorbent. The granulometric, elemental analysis, point of zero charge (pHPZC), radiochemical and structural characterization were conducted using X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) and gamma spectrometry techniques. The optimal conditions and key factors influencing the adsorption process were assessed using the response surface method (RSM). The adsorption capacity of the MFA adsorbent for Zn2+, Pb2+and As(V) removal, calculated by the Langmuir model, was found to be 33.13, 26.06, and 29.71 mg g−1, respectively. The kinetic and thermodynamic parameters indicated that the adsorption process is spontaneous and endothermic. Due to their low desorption potential of the exhausted adsorbents, their effective reuse was established to be feasible. For this reason, the valorization of this material as an additive in construction materials was thereafter studied, where testing its toxicity leaching (TCLP) as well as the mechanical properties of construction material containing exhausted MFA confirmed its safe use. Hence, this study points to a possible “two-in-one” reuse of coal ash, initially as an adsorbent and later as an additive in a construction material.

AB  - Zagađujuće materije iz otpadnih voda mogu se ukloniti različitim naprednim tehnikama prečišćavanja. Proces adsorpcije može se primeniti za uklanjanje teških metala iz otpadnih voda primenom brojnih materijala. U termoelektranama (TE) kao sporedni proizvod procesa sagorevanja uglja nastaju pepeo i šljaka. Cilj ovog rada je ispitivanje adsorpcionih svojstava pepela i šljake dodatkom cementa i kreča za uklanjanje jona teških metala (Cu2+, Zn2+, Pb2+ i Cd2+) iz vodenih rastvora. U radu su predstavljeni rezultati ispitivanja upotrebe modifikovanih oblika pepela i šljake kao adsorpcionog materijala. Najveću efikasnost uklanjanja ispitivanih jona pokazali su uzorci pepela i šljake iz TE Kostolac i TE Morava uz dodatak kreča, dok je uzorak pepela iz TE Kostolac uz dodatak cementa pokazao najmanji stepen izluživanja. Izvršena je selekcija materijala za dalja istraživanja koja obuhvataju optimizaciju procesa adsorpcije i karakterizaciju materijala.
AB  - Pollutants can be removed from wastewater by a variety advanced techniques for wastewater treatment. The adsorption process can be utilized for the removal of heavy metals from wastewater using numerous of materials. Fly ash and bottom ash are produced as a by-products of coal combustion in thermal power plants (TPP). The aim of this work has been to investigate the adsorption properties of a mixture made by adding cement and lime in fly ash and bottom ash to remove heavy metal ions (Cu2+, Zn2+, Pb2+ and  Cd2+) from aqueous solutions. This paper presents the results of a modified form of fly ash and bottom ash used as an adsorbent material. The highest removal efficiency of investigated ions has been found in samples of fly ash and bottom ash from TPP Kostolac and TPP Morava with the addition of lime, while the pattern of ash from TPP Kostolac with the addition of cement showed the smallest leaching level.    A selection of the material needs to be made in order to carry out further research that includs the optimization of the adsorption process and better char acterizing of adsorbent materials.

AB  - Testing the influence of two aggressive solutions - sulphate and nitrate on mortar and concrete was presented in this paper. Experimental work included testing of mortar prisms with 5 % special admixture. Also, four types of concrete were exposed to aggressive solutions. The chemical resistance was tested according to the Koch-Steinegger method. As a condition for resistance in aggressive solution means that flexural strength of mortar prisms is no less than 70 % of referent prisms cured in water it can be concluded that mortar and concrete made with combination of cement and admixture presented in this investigation are not resistant to ammonium nitrate solution, but are resistant to sulphate corrosion.
