AB  - Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change orwith intensified forest management practices. Using a newly established network of plots in beech forests across Europe,the aims of this study were to (i) distinguish soil properties and erodibility indices in relation to bedrock, (ii) determine geochemicalproperties and organic carbon (Corg) influencing erodibility, and (iii) assess the effect of soil depth on erodibilityindices. Seventy-six soil samples from 20 beech forests were collected in 11 countries to quantify soil properties influencingerodibility indices: clay ratio, modified clay ratio, sodium adsorption ratio, and oxides ratio. The results indicate that thedominant soil properties, determined by bedrock, that correlate with forest soil erodibility indices are Corg, pH, electricalconductivity, calcium and sodium ions concentrations, total water-soluble cations, and the percentage of sand. Accordingto the tested indices, soil susceptibility to erosion follows the order granite > andesite > sandstone > quartzite > limestone.Deeper soil horizons on granite are more susceptible to erosion than surface horizons are, but this is not the case forsoils on limestones. In conclusion, forest management should consider the predisposition of different soil types to erosion.

AB  - The objective of this study is geochronological investigation of sedimentological and inorganic composition, in the Danube Djerdap Lake sediments in order to obtain reliable information about former pollution. Eleven samples were taken from the 135-cm-deep sediment core drilled at the Orlova location. Since the core represents sediments deposited during 1972–2016, the sedimentation rate of ~ 3 cm year−1 was estimated. Grain size, mineralogical and geochemical composition was determined. Sediments are sandy silts and clayey silts, and only the deepest and shallowest layers contain > 30% of sand-size fraction. The highest concentrations of minor elements are found in the oldest sediment (1972–1977) as a consequence of the high flux of the material from variable sources. During the sedimentation period (1975–1990), the concentrations of analyzed elements are generally decreasing until the beginning of 1990s. After this period, there are two distinct decreases and two distinct increases in concentrations of elements. The fluctuations in minor element concentrations are a consequence of both natural and anthropogenic sources. Granitic rocks situated south are source of minerals that carry minor elements. Enrichment Factor, Geoaccumulation Index, Contamination Factor and Pollution Load Index indicate that concentrations of certain minor elements at specific depositional periods have anthropogenic source.

AB  - Fluorapatite doped with rare-earth elements has a wide-range of biomedical applications. Here, a new type of fluorapatite nanocrystals doped with praseodymium (FAP-Pr) with excitation-emission profiles in visible part of the spectrum is fabricated. Energy levels of Pr3+ activator ion contain metastable multiplet states that offer the possibility of efficient multicolor emission lines in FAP nanocrystals. Three types of FAP-Pr nanocrystals with 0.1%, 0.5% and 1% atomic percent of Pr3+ (along with the undoped FAP control sample) are studied. Their novel chemical production method is described, the FAP-Pr nanocrystals structure, biocompatibility and the suitability for cell imaging are analyzed. Physicochemical characterization confirms crystals down to nanometer size. In addition, quantum-chemical calculation predicts that Pr3+ ions are incorporated into the FAP crystal lattice at Ca2 (6 h) sites. In vitro viability results shows that FAP-Pr nanocrystals are nontoxic to live cells. Additionally, the cell uptake of the FAP-Pr nanocrystals is studied using fluorescence-based widefield and confocal microscopy. The nanocrystals show characteristic green emission at 545 nm (3P0→3H5 transition of Pr3+ ion) and orange emission at 600 nm (1D2→3H4), which we use to discriminate from cell autofluorescence background. Orthogonal projections across 3D confocal stacks show that the nanocrystals are able to enter the cells positioning themselves within the cytoplasm. Overall, the new FAP-Pr nanocrystals are biocompatible and of the tested types, the 0.5% Pr3+ doped nanocrystals show the highest promise as a tracking nanoparticle probe for bioimaging applications.

AB  - The analysis of isotope ratios of lead in the mushrooms and soil, where they were grown, assisted with a principal component analysis, offered a new perspective for understanding possible chemical environment in a real setup of those compartments. The content of lead and its isotope compositions were determined in soil samples and mushroom Macrolepiota procera from unpolluted area of Mountain Goč, Serbia. Sequential extraction procedure based on the Commission of the European Community Bureau of Reference (BCR) was applied on soil samples in order to determine the distribution of lead in the labile and un-labile fractions of the soil. Caps and stipes of mushrooms were subjected to microwave acid-assisted digestion prior to measurements by inductively coupled plasma quadrupole mass spectrometer for determination of lead content and lead isotope ratios. Information about the chemical fractionation of Pb in soil, Pb isotopic data from soil fractions and fruiting bodies allowed a more detailed insight on the uptake mechanisms. Lead was predominantly associated with reducible fraction (~ 60%). Only its small portion (∼ 1%) was present in the exchangeable and acid-extractable fractions suggesting the low mobility of Pb. Lead isotope analysis revealed the presence of anthropogenic lead in the surface soil. Significant lower 206Pb/207Pb compared with other fractions was found in exchangeable and acid-soluble fraction (1.331 ± 0.010), which corresponds to the isotope ratio of European gasoline. The highest 206Pb/207Pb ratio was observed in reducible fraction (1.162 ± 0.007), while in oxidizable and residual fraction, those values were similar (1.159 ± 0.006 and 1.159 ± 0.004, respectively). Distinction of exchangeable and acid-extractable fractions from others was also confirmed, for the first time, by principal component analysis. The analysis of four isotope ratios (206Pb/207Pb, 208Pb/206Pb, 206Pb/204Pb, and 207Pb/204Pb) indicated that the analyzed M. procera accumulates lead from the first two fractions of topsoil layers.

AB  - Due to the development of industry and population growth during the in recent years, there are problems with wastewater from production that needs to be addressed in an environmentally and economical way. All wastewaters from industry, no matter how they are created, contain harmful substances that may have some degree of toxicity, must be treated if their quality does not meet the legal requirements. The purpose of wastewater treatment is to remove
harmful substances, thereby reducing its pollution level, and at the same time, it also has a certain economic and environmental effect. Therefore, wastewater treatment was carried out in this work by precipitation using calcium oxide to remove colloidal substances and heavy metals. Most pollutants are of organic origin and their removal will be carried in this work out using advanced
oxidation processes using ozone, and ozone in combination with ultrasound to achieve water quality that complies with the law. The purification process will be optimized with respect to, method, time and amount of oxidizing agent applied. The degree of pollution of water by organic compounds will be determined on the basis of measurements of HPK, BOD and the concentration of heavy metals (lead, ferrum, chromium, copper, zinc, aluminum).

AB  - Magnetic and non-magnetic macroporous crosslinked copolymers of glycidyl methacrylate and trimethylolpropane trimethacrylate were prepared by suspension copolymerization and functionalized with diethylenetriamine. The samples were characterized by mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy analysis (FTIR-ATR), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), atomic force microscopy (AFM), transmission electron microscopy (TEM) and SQUID magnetometry. The FTIR-ATR analysis of synthesized magnetic nanocomposites confirmed the presence of magnetite and successful amino-functionalization. Non-functionalized and amino-functionalized nanocomposites exhibited superparamagnetic behavior at 300 K, with a saturation magnetization of 5.0 emu/g and 2.9 emu/g, respectively. TEM analysis of the magnetic nanocomposite has shown that magnetic nanoparticles were homogeneously dispersed in the polymer matrix. It was demonstrated that incorporation of magnetic nanoparticles enhanced the thermal stability of the magnetic nanocomposite in comparison to the initial non-magnetic macroporous copolymer.

AB  - With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. Quantum-chemical methods may be applied in structural modeling, prediction, and characterization of such molecules and reactions. Sorption of metal ions (Cu2+, Cd2+, Co2+, and Ni2+) to triethylenetetramine-functionalized copolymer poly(GMA-co-EGDMA)-teta was successfully modeled by quantum chemical calculations, at the B3LYP//6–311++G**/lanl2dz level. Optimized structures of metal complexes were used for calculation of real binding energy of metal ion within the complex (ΔEr). Solvent and hydrolyzation effects were essential for obtaining the objective values. Solvent effect was included in ΔEr by using the total solvation energy for reaction of formation of tetaOH complex (ΔEs1, the first approach) or by using dehydration energy of free metal ion (ΔEs2, the second approach). Experimental results were confirmed in our theoretical analyses (using the second approach).

AB  - Polymer-based, highly porous nanocomposites with functionalized ligands attached to the core structure are extremely efficient in the detection, removal and recovery of metals through the process of sorption. Quantum-chemical models could be helpful for sorption process analyses. The sorption of Cu(II) ions by amino-functionalized chelating macroporous copolymers poly(GMA-co-EGDMA)-amine and sorption selectivity of the subject copolymers, ethylenediamine (en), diethylenetriamine (dien) and triethylenetetramine (trien), were successfully modelled by quantum chemical calculations. Considering the crystal structures from CSD and experimental conditions during the formation of metal complexes, the most frequent mononuclear complexes are those with the tetradentate teta ligand, while binuclear complexes are formed when the metal ion is in large excess. Although the en-copolymer was the most effective functionalized one, higher maximum sorption capacities (Qmax) were observed for the dien- and trien-copolymers, due to their abilities to form binuclear complexes. The enthalpy term has the greatest contribution to the total Gibbs energy change of reaction for the formation of mononuclear Cu(II) complexes (ΔGaq), while the solvation energy of the reaction has the greatest contribution in the formation of binuclear complexes. The results of the study indicate that small amines with the ability to form binuclear complex are the best choice for functionalization of the considered copolymer.
AB  - Квантнохемијско моделовање се показало као корисна алатка за разјашњавање процеса сорпције, као и за предвиђање структуре насталих производа те сорпције. Уз помоћ квантнохемијских прорачуна успешно су моделаовани процеси сорпције Cu(II) јона и селективност тих сорпција на амино-функционализованим хелатним кополимерима поли(глицидил-метакрилат-ко-етиленгликол-диметакрилат) (поли(GMA-ко- 
-ЕGDMA)) са различитим бројем амино група у свом саставу (етилен (-en), диетилентриамин (-dien) и триетилентетраамин (-trien) кополимери). Узимајући у обзир кристалне структуре из CSD и експерименталне услове приликом формирања комплекса са Cu(II) јоном, дошли смо до закључака да су најчешће структуре мононуклеарних комплекса са тетрадентатно везаним лигандима, али да се бинуклеарни комплекси јављају
када је јон металa у вишку у односу на кополимер. Без обзира на то што је кополимер са en-лигандима најефикасније функционализован, најбоља сорпција Cu(II) јона (Qmax) се, 
ипак одиграва на dien- и trien-кополимерима. Овакав резултат је последица боље способности dien и trien лиганада за грађење бинуклеарних комплекса са Cu(II) јонима. Највећи допринос укупној промени Гибсове енергије реакције грађења мононуклеарног Cu(II) комплекса (ΔGaq) потиче од енталпијског члана.

Makroporozni nanokompoziti dobijeni su in-situ suspenzionom kopolimerizacijom tako što su nanočestice magnetita dodate u početnu reakcionu smešu za sintezu nemagnetičnih uzoraka makroporoznih kopolimera. Modifikacija uzoraka nanokompozita izvršena je u reakciji nanokompozita sa dietilentriaminom pri čemu su dobijeni amino-funkcionalizovani nanokompoziti. Dobijeni uzorci kopolimera i nanokompozita detaljno su analizirani infracrvenom spektroskopijom sa Furijevom transformacijom (FTIR), rendgenskom difrakcionom analizom (XRD), živinom porozimetrijom, skenirajućom elektronskom mikroskopijom sa energetski disperzivnom spektroskopijom X-zraka (SEM-EDX), transmisionom elektronskom mikroskopijom (TEM), mikroskopijom atomskih sila (AFM), termogravimetrijskom analizom (TGA) i elementarnom analizom (CHN). Magnetna svojstva nefunkcionalizovanih i amino-funkcionalizovanih makroporoznih nanokompozita analizirana su pomoću SQUID magnetometra. Na uzorcima amino-funkcionalizovanih makroporoznih nanokompozita vršena je sorpcija i razdvajanje oksianjona Mo(VI) i Re(VII) iz vodenih rastvora. Ispitan je uticaj pH vrednosti rastvora, vremena kontakta, temperature i početne koncentracije jona metala na efikasnost i kapacitet sorpcije, kao i uticaj jonske jačine rastvora i koncentracije koegzistirajućih anjona i katjona na kapacitet sorpcije oksianjona Mo(VI) i Re(VII). Eksperimentalni rezultati korišćeni su za izučavanje mehanizma sorpcije primenom četiri kinetička modela: modeli pseudo-prvog reda i pseudo-drugog reda, model unutar-čestične difuzije i Bojdov model. Ravnotežni podaci su analizirani primenom Lengmirovog i Frojndlihovog adsorpcionog modela izoterme.Na osnovu eksperimentalnih rezultata može se zaključiti da su amino-funkcionalizovani makroporoyni nanokompoziti pogodni kao sorbenti za selektivnorazdvajanje oksianjona Mo(VI) i Re(VII) iz vodenih rastvora. Pokazalo se da Lengmirov model adsorpcione izoterme najbolje opisuje sorpciju jona metala na amino-funkcionalizovanim nanokompozitima i da na ukupnu brzinu sorpcije utiče unutar-čestična difuzija uz izvestan uticaj difuzije kroz film.
AB  - Macroporous crosslinked copolymers and nanocomposites of glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) or trimethylolpropane trimethacrylate (TMPTMA) were prepared by suspension copolymerization. The nanocomposites were synthesized with addition of magnetite nanoparticles in the reaction mixture used for synthesis of non-magnetic copolymer samples. The samples of amino-functionalized nanocomposites were prepared by modification of nanocomposite samples in reaction with diethylenetriamine. The obtained samples were characterized in detail by elemental analysis, Fourier transform infrared spectroscopy analysis (ATR-FTIR), X-ray diffractometry (XRD), mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), transmission electron microscopy (TEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA) and SQUID magnetometry. The chosen amino-functionalized nanocomposite samples were tested as a potential sorbents for sorption and separation of Mo(VI) and Re(VII) oxyanions from aqueos solutions. The effects of pH, contact time, temperature and initial concentration of the metal ions on the sorption capacity and the sorption efficiency were investigated. Also, the influence of ionic strength and possible interfering of cations and anions on the sorption capacity was investigated. The sorption behavior and rate controlling mechanisms were analysed using four kinetic models: pseudo-first order, pseudo-second order, intraparticle diffusion and Boyd models. Equilibrium data were analysed with Langmuir and Freundlich adorption isotherm models.All results indicate that the amino-functionalized nanocomposites could be used as promising sorbents for sorption and separation of Mo(VI) and Re(VII) oxyanions from aqueos solutions. The isotherm data were best fitted Langmuir model for both amino-functionalized nanocomposites. The sorption kinetics was determined to begoverned by both the intraparticle diffusion and the external film diffusion to a lesser extent.

AB  - Speciation of Cu(II), Cd(II) and Ni(II) ions from aqueous solutions by means of the magnetic amino-functionalized polymer/bentonite composite based on methacrylates was investigated. The influence of contact time and initial concentration was monitored and the obtained data were analyzed by kinetic models, as well as the Langmuir and Freundlich adsorption isotherms.  The composite was shown to be very efficient in the sorption of investigated ions, which can effectively be removed from aqueous solutions by applying the external magnetic field.

AB  - The presented study describes macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [PGME] functionalized with diethylenetriamine [PGME-deta] as a potential recovery agent for Mo(VI) oxyanions from aqueous solutions. Sorption studies were carried out by varying experimental conditions (pH, time, concentration, temperature). Kinetics of Mo(VI) sorption was investigated in batch (static) experiments, in the temperature range 298-343K. Sorption dynamics data were fitted to seven chemical-reaction and particle-diffusion models. The kinetics studies showed that Mo(VI) sorption adhered to the pseudo-second-order model under all investigated operating conditions. The sorption kinetics was determined to be governed by both the intraparticle diffusion and the external film diffusion to a lesser extent. The temperature rise promotes the molybdate species removal, with the maximum experimental uptake capacity of 4.02mmolg- 1 at 298K, at the selected pH which is consistent with the predominance range of hydrolized polynuclear Mo(VI) forms and optimum electrostatic attraction.

AB  - Recent advances in material technologies have resulted in the preparation of novel polymer/clay composites with improved thermal, mechanical, optoelectronic/ magnetic properties and increased biodegradability [1]. In this study, six samples of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) nanocomposites with organically-modified montmorillonite clay Cloisite 30B® (C30B), were prepared via suspension copolymerization. In order to obtain nanocomposites with fine spherical beads of regular shape and satisfying thermal stability the optimization of the synthesis conditions was performed. Firstly, the influence of the poly(N-vinyl pyrrolidone) (PVP) quantity in the aqueous phase was varied (1, 3 and 5 wt.%) at a constant stirring rate of 250 rpm and constant clay content C30B (10 wt.%). In the second phase of the optimization of the preparation, samples with a constant composition of the composite reaction mixture (5 wt.% PVP and 10 wt.% C30B) at a stirring rate of 250, 325 and 400 rpm, were prepared. According to the obtained results, it was concluded that the optimal conditions for preparation of these composites are 5 wt.% of PVP and 400 rpm. The prepared nanocomposites were characterized with Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) in air. The structure of the prepared nanocomposites was confirmed with FTIR spectroscopy. According to the obtained SEM microphotographs the fine spherical beads, with desired size and homogeneous morphology, were prepared. Furthermore, SEM analysis was also showed that clay nanoparticles are homogeneously dispersed both inside surface and cross-section area. The incorporation of C30B clay increased the thermal stability of the prepared polymer/clay nanocomposites in comparison to the pure PGME copolymer.

AB  - Liming is a common practice in the treatment of acidic and metal contaminated soils, aiming at pH regulation, enhancing of the nutrient availability and attenuation of trace metals mobility. Replacement of natural limestone with alternative soil alkalizers found among waste materials represents a step towards sustainable resource management and reduced waste storage. In this study, waste seashells (SW) and red mud (RM) were applied in different doses to the soil sampled in the vicinity of mining and smelting complex. The soil was characterized by acidic reaction (pH 4.93), increased Cu concentration (219.2 mg/kg) and a very low level of P-supply (3.61 mg P2O5/100 g). The study aimed to quantify and compare additive-induced effects onto soil physicochemical properties, the status of macronutrients and distribution of trace metals. Targeted effect on soil pH was achieved with SW dose of 0.3% and RM dose of 2%. RM was found to be a source of available P and gave rise to the available P concentrations in the soil. Medium level of P-supply (15.60 mg P2O5/100 g) was achieved with RM dose of 5%, however, the increase in soil salinity and total trace elements concentrations have become significant adverse effects at such dose. The decrease in the ion-exchangeable content of Cu and other trace metals was in correlation with the increase in soil pH after the treatments. Redistribution of metal cations was mainly directed to carbonate/acid soluble and Fe, Mn-oxide bonded fraction after SW addition. Even though trace metals concentration has increased in the soil after application of the RM, they were principally found in the residual fraction. The results emphasize low amounts of contained trace elements and lower doses for achieving targeted effects on pH and metal mobility as the main benefits of SW treatments. On the other hand, moderate and controlled use of RM may represent multiple benefits in terms of simultaneous pH regulation, P-supply, and reduced trace metals mobility.

AB  - In the present study we have analyzed effects of Ag+ ions doping on energetic profiles of nanophosphors materials based on fluorapatite crystal system. The UV radiation absorption and luminescence properties of monophase fluorapatite (FAP) and Ag+ doped fluorapatite (AgFAP) nanomaterials obtained by neutralization method were investigated using the photoluminescence spectrophotometry. The excitation-emission profiles of nanomaterials were analyzed statistically by MCR-ALS method and number of fluorophores was extracted. FAP lattice absorbed light at 350 nm in the UVA part of spectrum, and with increasing concentration of Ag+ ions new absorption maximum appeared at 270 nm in the UVC part. Fluorescence of FAP nanoparticles was in violet region of visible part of the spectrum, with a red shift to the green region when Ag+ was doped in lattice. MCR-ALS analyses of fluorescence spectra confirm formation of two maxima, at 484 and 505 nm, as a consequence of Ag+ ions doping in FAP lattice at Ca1 (4f) sites. The results of quantum chemical calculations showed that an Ag+ ion is stronger bonded to the binding site 1 (-1352:6 kcal/mol) than to the binding site 2 (-1249:0 kcal/mol). Considering that AgFAP1 nanopowder absorbs photons over all part of UV radiation spectrum, this material might be used as potential radiation protective nanomaterial.

AB  - The Great War Island (GWI) is an area of importance for the protection of the environment, cultural and historical heritage of Belgrade, Serbia. According to the International Union for Conservation of Nature (IUCN) this area belongs to the IV category - Habitats and Other Regulated Areas. The main objectives of this paper are to evaluate the potential impacts of pollution on ecosystem services of the Great War Island and to explore different scenarios for future urban development of the Great War Island that will have implication for human well-being. The aims of this paper are set up based on the evaluation of ecosystem services of the Great War Island and assessment of the pollution status of the Great War Island. In order to evaluate pollution status of the GWI inorganic and organic composition of sediments were examined. Additionally, the content of microelements was determined in the leaves of the Salix alba L. Pollution indices indicate that all investigated sampling sites are polluted and correspond to high and very high degree of contamination. Cd and Cu show high to extremely high degree of contamination while Sb has extremely high degree of contamination. Content of As, Co, Cu, Ni and Zn in leaves of Salix alba L. is in sufficient to normal range, while content of Cd is between the sufficient and excessive values generalized for various species. Typical oil distributions of terpanes and steranes and values of the corresponding maturity parameters clearly indicated that the sediments of the GWI, in addition to native organic matter, contained oil pollutants of anthropogenic origin. GWI provides provisioning, regulating, supporting and cultural ecosystem services. In relation to ecosystem services two possible scenarios can be predicted: first - losing the status of a protected area due to urbanization; and the second - increasing the degree of protection by admission into international protection lists

FT-IR spectra of the prepared films propose that carboxyl group from pectin are mainly involved in interactions with CMC, whereas −OH groups are mainly involved in self-associated hydrogen bonding of neat polymers. Further, an addition of carboxymethyl cellulose improved mechanical properties compared to pure pectin films, while TGA analysis confirmed satisfying thermal stability regarding their potential application as packaging material. Finally, water vapor permeability values are in the range of 1.32 × 10−7 up to 2.03 × 10−7 g/m h Pa.

AB  - The aim of this study was the development of novel polysaccharide based films intended to be used as edible food packaging material. The films were prepared by solution casting method using highly methoxylated pectin (PEC) and poly(ethylene glycol) (PEG) of various molecular weights (400, 600 and 1000 gmol(-1)) in different ratios (5:1, 3:1 and 1:1). The film formation was supported by hydrogen bonding between PEC and PEG, which was evidenced by means of ATR-FTIR and NMR analysis. TGA revealed that generally PEG behaves like a pro-degrading agent for pectin, except in the case of PEC/PEG film with a ratio of 1:1. Furthermore, DSC thermograms indicated that PEG1000 exists as a separate phase in the pectin matrix while the formulations with PEG400 and PEG600 showed mainly amorphous morphology. The addition of PEG enhanced the plasticization of PEC films, as evidenced by progressive decreasing of the glass transition temperature values (T-g). The tensile test measurements showed that increasing concentration of PEG produced weaker and more flexibile films. Due to the increased molecular mobility, the pectin phase became more permeable to water vapor as the PEG concentration increased. The obtained results showed that the combination of both polymers resulted in interesting bio -inspired edible films with the potential to compete with commercially used synthetic package materials.

AB  - In this paper, we intend to show the importance of the bifurcation analysis in understanding of an oscillatory process. Hence, we use the bifurcation diagram of the Bray-Liebhafsky reaction performed in continuous well-stirred tank reactor under controlled temperature variations for the determination of the activation energies as well as rate constants of particular steps appearing in the kinetic model of oscillatory reaction mechanism. This approach has led us to the development of general procedure for treatment of experimentally obtained data and extracting kinetic parameters from them, which was very important considering that some rate constants of the already proposed model could not be determined experimentally and have to be fitted (or guessed). Also, the proposed approach has the potential to inspire the refinement of already proposed models and the development of a new one that will be able to reproduce experimentally obtained system's dynamical features more successfully. In particular, the dynamic states of the Bray-Liebhafsky oscillatory reaction have been analyzed experimentally and numerically using already proposed model together with qualitative and quantitative analysis of bifurcation diagrams in both cases.

AB  - The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance cations of zeolite, contact time and temperature determined the adsorption efficiency. The maximum removal efficiency of 98.8% and K (d) value (2.06 x 10(-4) cm(3) g(-1)) was achieved using CoY (zeolite type Y). The kinetics of technetium adsorption followed the pseudo-second order model. The TcO2 adsorption is mainly due to the hydrogen bonds between protons of the zeolitic structural OH groups (Bronsted acid center) and oxygen from the TcO2 (-).

AB  - Segmented polyurethanes (SPU) are multiblock copolymers consisted of hard (HS) and soft segments (SS). HS usually form crystalline domains that are responsible for good mechanical properties, while SS represent amorphous matrix that contributes to good elastomeric properties, hydrophobicity and inertness of the SPUs. Furthermore, the morphology of the SPUs is one of the main factors that determine their physical and chemical properties. Moreover, thermodynamic incompatibility between HS and SS leads to the formation of microphase separation within the 
SPUs. Properties of SPUs mostly come from their different composition and microphase separation between segments.

Bentonite as well has been proved as an excellent adsorbent for heavy metals and organic pollutants removal from wastewaters. In order to combine favorable characteristics of magnetite nanoparticles (easy separation using magnetic field), bentonite (large surface area, high chemical and mechanical stability, low-cost and easily available) and macroporous copolymer (selectivity, possibility of 
additional functionalization, high sorption rate and capacity, recycling capability) a novel magnetic polymer/bentonite nanocomposite was synthesized.
