AB  - A novel adsorbents, 6-arm amino polyethylene glycol functionalized multiwall carbon nanotubes (PEG/MWCNT) loaded with alpha-FeOOH (Fe/PEG/MWCNT), and hybrid alpha-FeOOH/alpha-MnO2 nano-deposit (Fe-Mn/PEG/MWCNT) were used for As(V) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on adsorption efficiency was studied. Time-dependent adsorption was best described by pseudo-second-order kinetic model and Weber-Morris model which predicted intra-particle diffusion as a rate controlling step of overall process. Competitive kinetic study in the presence of interfering ions shows low detrimental effect on both capacity and kinetic of As(V) removal. Thermodynamic parameters showed that the adsorption was spontaneous and endothermic processes. Influences of the pH, iron oxide loading and interfering ions were modeled by using Visual MINTEQ software. High adsorption capacities: 49.39 and 59.78 mg g(-1) were obtained for Fe/- and Fe-Mn/PEG/MWCNT, respectively, and multi-cycle reusability indicated high applicability of obtained material. Two step removal process, in a batch study, was successfully performed by using PEG/MWCNT for cations removal in the first step, and Fe or Fe-Mn/PEG/MWCNT for As(V) removal in the second.

AB  - Unsaturated polyester resin (UPe)-based nanocomposites and fumed silica Aerosil R812S, R805 and R816, and R200 modified with phenyl terminal group, R200NPh, were prepared. UPe resins were synthesized from maleic anhydride and products of glycolysis, obtained by polyethylene terephthalate depolymerization with dipropylene glycol in the presence of tetrabutyl titanate catalyst. The obtained unsaturated polyesters were characterized by acid, hydroxyl, and iodine values and by FTIR and NMR analysis. The microstructural analysis of the prepared nanocomposites, performed by using transmission electron microscopy, confirmed that silica nanoparticles formed chain-like aggregates in the polymer matrix. The presence of modified silica nanoparticles had no influence on the glass transition temperature and thermal stability of polyester matrix. The tensile modulus, stress at break, and hardness of cured products increased with increasing silica content. The impact strength of cured samples was not influenced by the silica content.

AB  - The state of the tautomeric equilibria of 2(6)-hydroxy-4-methyl-6(2)-oxo-1-(substituted phenyl)-1,2(1,6)-dihydropyridine-3-carbonitriles, 2-PY/6-PY, was evaluated using experimental and theoretical methodology. The experimental data were interpreted with the aid of time-dependent density functional (TD-DFT) method. Electron charge density was obtained by the use of Quantum Theory of Atoms in Molecules, i.e. Baders analysis. Linear solvation energy relationships (LSER) rationalized solvent influence on tautomeric equilibrium. Linear free energy relationships (LFERs) were applied to the substituent-induced NMR chemical shifts (SCS) using SSP (single substituent parameter) and DSP (dual substituent parameter) model. Theoretical calculations and obtained correlations gave insight into the influence of molecular conformation on the transmission of substituent electronic effects, as well as on different solvent solute interactions, and the state of tautomeric equilibrium.

AB  - The optimized methods for N-alkyl and N,N-dialkyl substituted thioureas synthesis starting from ammonium thiocyanates, waste water constituent from the production of tetramethylthiuram monosulfide (TMTS), and alkyl amine, are presented in this work., Thioureas synthesis was developed in two ways: Method I-reaction of the thiocyanate and alkylamine in the presence of hydrochloric acid; Method II-reaction of the thiocyanate with benzoyl chloride following by amine addition in the first step, and base hydrolysis in the second step. The structure of the synthesized compounds was confirmed by IR, H-1- and C-13-NMR and MS instrumental methods, and purity was determined by high-performance liquid chromatography method. It is shown that the proposed methods offer a high degree of conversion and purity of product, absence of by-products and technological applicability at industrial scale. Considering the importance of the tetramethylthiuram disulfide (TMTD) and TMTS as vulcanization accelerators as well as thiourea as the pharmacologically active compounds, it can be said that application of the optimized methods of thiourea synthesis will provide significant improvement in sustainable development and implementation of eco-friendly production technology.

AB  - Optimization of the synthesis of cross-linked macroporous polymer impregnated with hydrous iron oxide and post-process of obtained material by application of freeze/drying technique, produces high performance adsorbent applicable for efficient arsenic removal. Characterization and analysis of adsorbent performances encompass material characterization, equilibrium and kinetic study, influences of interfering ions and modeling of adsorption data in ion free and competitive conditions. Kinetic study, i.e. fitting by Weber-Morris model and single resistance mass transfer model predicts intra-particle diffusion as a rate-controlling step. Thermodynamic parameters indicate endothermic, feasible and spontaneous nature of adsorption process. Competitive kinetic study in the presence of interfering ions shows low detrimental effect on both capacity and kinetic of arsenic removal. Visual MINTEQ modeling software was used for the prediction of adsorbent performances and interfering ion influences. Preliminary fixed-bed column study was accomplished by the use of Bohart-Adams, Yoon-Nelson, Thomas and Modified dose-response model. High arsenic removal capacity of 31.0 mg g(-1), at 25 degrees C, and multi-cycle reusability of ER/DETA/FO/FD, significantly affects the affordability of techno-economic indicators based on the operating costs of the process.

AB  - The Republic of Serbia is a good example of a developing country with a water management system that has not been adequately transitioned to address the need of the new socio-economic paradigm. Consequently, more than 30% of generated potable water is lost in transportation, sewage collection and treatment significantly lag behind water supply and only 10% of the collected sewage receiving adequate treatment witch further burdens the already unsatisfying quality of water resources. In order to mitigate the upcoming effects of climate change and successfully manage the water resources for the next generations, the goal of this study is to identify and evaluate the existing barriers that hinder the development and implementation of an integrated national water resources management system. To achieve this goal, water resources management system in Serbia is examined through the prism of regulations, management, engineering, and education, which represent principal pillars of every national socio-economic system. The key findings and the outcomes of this study reveals that an in-depth analysis of existing situation and identification of barriers represent important initial steps in process of developing and implementing an integrated national water management system.

AB  - An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system goethite/alpha-MnO2 (calcined eggshell/goethite/alpha-MnO2; sorbent 3). Methods and processes for preparation of novel adsorbents were defined and obtained materials were characterized by BET, XRD, SEM and FTIR analysis. The influence of functionalization methods, solution pH, contact time, temperature, interfering ions and initial arsenate concentration on efficiencies of arsenate adsorption were studied in a batch system. Based on the orthogonal distance regression (ODR) fitting, using R-2, MARE and RMSRE statistical criteria, Langmuir and Sips equations were chosen for description of adsorption equilibriums on sorbents 1 and 3, respectively. The maximum adsorption capacities of 33.38 mg g(-1), 13.54 mg g(-1) and 47.04 mg g(-1) for sorbents 1-3, respectively, were obtained. Time-dependent study revealed that pseudo-second-order equation fitted well the kinetic data, while the Weber Morison model predicted intra-particle diffusion as main adsorption rate controlling step. Thermodynamic parameters indicated exothermic, feasible and spontaneous nature of adsorption process on sorbents I and 3. Results of Visual MINTEQ equilibrium speciation modeling program was used for studying pH, ionic strength and interfering ions influences on arsenate adsorption. (C) 2013 Elsevier B.V.

AB  - The tautomeric equilibria between 2-pyridone and 2-hydroxypyridine forms of methoxy, chloro, and nitro derivatives of 3-cyano-4-(2-, 3-, and 4-substituted phenyl)-6-phenyl-2(1H)-pyridones were evaluated from UV/Vis spectral data. Linear solvation energy relationships of Kamlet-Taft and Catalan-rationalized solvent have influence on tautomeric equilibria. Transmission of substituent effect was analyzed by the Hammett equation. Quantum chemical calculations were performed by density functional theory (B3LYP). The experimental data were interpreted with the aid of time-dependent density functional method. Electron density distribution was analyzed by Baders analysis. It was found that substituents of different electronic properties change the extent of conjugation, and affect intramolecular charge transfer character. Theoretical calculations and experimental results gave insight into the influence of the molecular conformation on the transmission of substituent effects, as well as on contribution of different solvent-solute interactions.

AB  - A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 (calcite/goethite/alpha-MnO2; sorbent 4) in order to obtain a cheap hybrid materials for simple and effective arsenate removal from aqueous solutions. The adsorption ability of synthesized adsorbents was studied as a function of functionalization methods, pH, contact time, temperature and ultrasonic treatment. Comparison of the adsorptive effectiveness of synthesized adsorbents for arsenate removal, under ultrasound treatment and classical stirring method, has shown better performance of the former one reaching maximum adsorption capacities of 1.73, 21.00, 10.36 and 41.94 mg g(-1), for sorbents 1-4, respectively.
