AB  - The textile industry is one of the major polluters of the environment, primarily due to the types and quantities of wastewater it produces. It is estimated that 20% of global water pollution is caused by textile processing, meaning that these processes generate enormous amounts of wastewater. Generally, this wastewater contains high levels of suspended solids, dyes, salts, pesticides, non-biodegradable organic substances, and heavy metals. The decline in water quality, along with increasingly stringent environmental protection regulations, has led the textile industry to turn to sustainable wastewater treatment methods that help reduce the global water footprint. This paper reviews some viable methods used for the treatment of wastewater originating from the textile industry. The focus is on advanced treatment techniques, such as adsorption, membrane-based filtration, electrochemical processes, and advanced oxidation. These methods offer potential solutions to mitigate the environmental impact of textile wastewater and promote sustainable water management practices.

AB  - Three-dimensional hierarchical porous carbons (HPCs) created through hydrothermal carbonization and the subsequent chemical activation of miscanthus were tested as adsorbents of Pb2+ and methylene blue from the aqueous solution. The HPC pore structure was customized using various hydrochar precursors obtained through a longer reaction time and by adding acetic acid. HPC obtained from hydrochar derived from acetic acid’s addition exhibited the highest specific surface area due to a larger micropore volume. This adsorbent proved to be the most efficient in removing lead from aqueous solutions. The Langmuir isotherm best described the lead adsorption process onto HPC with qm = 155.6 mg g−1 and the pseudo-second-order kinetic model. HPC obtained from hydrochar produced with a longer reaction time exhibited improved methylene blue adsorption properties. The pseudo-second-order kinetic model and the Freundlich isotherm best described the experimental data. The theoretical maximum adsorption capacity for methylene blue was 316.0 mg g−1. The type of hydrochar significantly impacted the yield and physical structure of HPCs, while having a lesser effect on the composition of surface functional groups. The results revealed the binding mechanism of each pollutant, highlighting the importance of biomass pretreatment on the structure of the resulting HPC and its effectiveness in water purification.

AB  - Zinc-air batteries belong to the group of green and sustainable energy storage systems, and as such, they attract a huge attention of both academic and technological communities. For this system, the alkaline electrolytes of zinc with high concentrations of ZnO and KOH are used. Morphology of zinc electrodeposits is characterized by the scanning electron microscopy (SEM) technique, and it was found that it depended on an overpotential of the electrodeposition with a strong contribution of a length of the electrodeposition time on the final shape. Variety of morphological shapes was observed: irregular and regular grains including those hexagonal shape were predominately formed at the overpotential belonging to the plateau of the limiting diffusion current density. The compact both regular and irregular dendrites were formed at this overpotential with the longer electrodeposition time. The 2D (two-dimensional) and 3D (three-dimensional) dendrites were formed at overpotentials outside the plateau of the limiting diffusion current density, in the zone of the rapid growth of the current density with the increase of the overpotential. In this zone, hydrogen evolution reaction as the second reaction to Zn electrolysis at high overpotentials started to take place. It is manifested by the appearance of craters on the surface of the electrode, which originate from detached hydrogen bubbles. All morpholical forms were explained and discussed applying the basic laws of electrocrystallization.

AB  - Correlation between morphology of electrolytically produced copper thin films and their hardness has been considered. The Cu films were electrodeposited by galvanostatic (DC) and by the pulsating current (PC) regimes on cathodes of limiting values of hardness (Cu, brass, and Si(111)) from the basic sulfate electrolytes without and with addition of leveling/brightening additives, without and with various ways of electrolyte stirring (ultrasound and magnetic stirring), and characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM) techniques. Hardness of Cu films was determined by microindentation and by application of composite hardness models (CHMs), such as Cheng–Gao (C–G) and Korsunsky (K), with the aim to eliminate a contribution of cathode hardness in the measured film hardness and to determine the absolute hardness of the Cu films. The fine-grained films obtained from the basic sulfate electrolyte were harder than the smooth film obtained from the electrolyte with additives and that obtained by the PC regime, indicating that the PC produced film represents transitional form between these two types of the films. The obtained values of the absolute film hardness in the 1.135–1.647 GPa range were in line with already published values for the electrolytically produced Cu thin films, clearly indicating on successful implementation of CHMs in determination of the absolute hardness of thin films. Correlation between morphology and hardness of Cu films was discussed by the basic laws of electrocrystallization and phenomena on boundary among grains during microindentation processes.

AB  - The alkaline electrolytes of zinc are widely used in a Zn-air secondary batteries which represent promising candidate for energy storage with many advantages relative to the other types, such as Li-air, Al-air, and Mg-air batteries. These advantages are related with an abundance of Zn, low toxicity, and low cost, as well as by the fact that Zn possess a relatively high specific energy density. One of the largest problems in a development of Zn-air batteries is dendritic growth caused by the uneven deposition of zinc in the charging process. The solving of this problem implies the good knowledge of all phenomena related with Zn deposition, and regarding it, this study aims to establish a correlation between morphology and structure of electrolytically produced Zn irregular forms, especially Zn dendrites. Zinc was electrodeposited potentiostatically from the concentrated electrolyte (0.35 M ZnO in 6.0 M KOH) at overpotentials belonging to the end of the plateau of the limiting diffusion current density (η = 160 mV), and to the zone of the fast growth of the current density after the end of the plateau of the limiting diffusion current density (η = 220 and 280 mV). Morphology and structure of Zn particles were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD), respectively.
Morphology of Zn electrodeposits changed with the increase of overpotential of the electrodeposition from regular hexagonal and other regular crystal forms to the mixture of 2D (two dimensional) and 3D (three dimensional) dendrites. The increase of overpotential of the electrodeposition led to an appearing and then intensification of hydrogen evolution reaction as a parallel reaction during Zn electrodeposition at the high overpotentials.
In spite of various shapes, Zn particles electrodeposited at all three overpotentials exhibited the strong (002) preferred orientation. The explanation for this predominant preferred orientation can be found in an analogy with a electrolytic growth of lead dendrites from the concentrated electrolyte. Although these two metals belong to different types of crystal lattice (Pb - face-cantered cubic type, and Zn - hexagonal close packed type), the common characteristic of dendritic growth is the preferred orientation in a crystal plane with the lowest surface energy. Namely, during growth of dendrites, this plane survives, while other crystal planes with the higher surface energy values disappear, causing the predominant orientation of Zn disperse forms in (002) crystal plane. In this way, interior of the Zn dendrites is constructed from (002) crystal plane, while tips and edges of Zn dendrites and other types of particles are from other crystal planes.

AB  - Textile industry wastewater is a significant source of pollution, often containing hazardous organic
dyes like Crystal Violet (CV). Photocatalytic degradation using semiconductor materials such as
titanium dioxide (TiO2) presents a promising solution for wastewater treatment due to its effectiveness
in breaking down organic pollutants under UV irradiation. This study investigates the efficiency of
TiO2 as a catalyst for the photodegradation of CV removed from textile wastewater. Experimental
trials were conducted in a batch reactor under UV irradiation, with CV (20 ppm) and varying
concentrations of TiO2 catalyst. Results revealed a significant reduction in CV concentration with
increasing catalyst dosage (to 0.1 g/L) and irradiation time. The optimal conditions for maximum
degradation efficiency were determined, highlighting the potential of TiO2 photocatalysis for textile
wastewater treatment. Furthermore, the kinetics of CV degradation were analyzed to understand the
reaction mechanism and rate. The degradation of the dye (20 ppm) was 98% for 95 min with 0.1 mg/L
TiO2. This research contributes to developing sustainable and efficient methods for treating textile
wastewater, addressing environmental concerns associated with dye pollution.

AB  - Production of organic dyes has been constantly increasing in the last decades, hence their us-age leaves a huge environmental impact usually on aquatic biota. Wastewaters carrying dissolved dyes are toxic to all organisms existing in water, therefore such wastewater streams have to be ap-propriately treated before they can be released into the environment. Development of effective ad-sorbents, which can be used in wastewater treatment, is mandatory. Another concern in the produc-tion of sorbing materials is the formation of spent acids or bases since they are commonly used for the activation of adsorbents. Spent acid liquor produced during the activation of expanded vermicu-lite (EVer) is utilized as the start material for the preparation of layered double hydroxide (LDH-EVer) by the method of co-precipitation process at low supersaturation. The prepared adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy with X-ray energy dispersive spectroscopy (SEM-EDS). Fabricated material is utilized as an adsor-bent of methyl orange dye from aqueous solutions. During the experiments, contact time were varied and thus the rate of adsorption is determined. The obtained results show a high adsorption capacity of 63 mg g-1.

Development of effective ad-sorbents, which can be used in wastewater treatment, is mandatory. Another concern in the produc-tion of sorbing materials is the formation of spent acids or bases since they are commonly used for the activation of adsorbents. Spent acid liquor produced during the activation of expanded vermicu-lite (EVer) is utilized as the start material for the preparation of layered double hydroxide (LDH-EVer) by the method of co-precipitation process at low supersaturation. The prepared adsorbent was characterized by Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy with X-ray energy dispersive spectroscopy (SEM-EDS). Fabricated material is utilized as an adsor-bent of methyl orange dye from aqueous solutions. During the experiments, contact time were varied and thus the rate of adsorption is determined. The obtained results show a high adsorption capacity of 63 mg g-1.",

AB  - The contamination of the water bodies by diesel oil (DO) and its water-soluble fraction (WSF) represents one of the most challenging tasks in the management of polluted water streams. This paper contains data related to the synthesis and characteristics of the plum stone biochar material (PmS-B), which was made from waste plum stones (PmS), along with its possible application in the sorption of the WSF of DO from contaminated water. Techniques applied in sample characterisation and comparisons were: Elemental Organic Analysis (EOA), Scanning Electron Microscopy−Energy Dispersive X-ray Spectroscopy (SEM-EDX), Fourier Transform Infrared Spectroscopy (FTIR), pH (pHsus) and point of zero charge (pHpzc). In order to increase the overall efficiency of the removal process, sorption and bioremediation were subsequently combined. Firstly, PmS-B was used as a sorbent of WSF, and then the remaining solution was additionally treated with a specific consortium of microorganisms. After the first treatment phase, the initial concentration of diesel WSF was reduced by more than 90%, where most of the aromatic components of DO were removed by sorption. The sorption equilibrium results were best fitted by the Sips isotherm model, where the maximum sorption capacity was found to be 40.72 mg/g. The rest of the hydrocarbon components that remained in the solution were further subjected to the biodegradation process by a consortium of microorganisms. Microbial degradation lasted 19 days and reduced the total diesel WSF concentration to 0.46 mg/L. In order to confirm the non-toxicity of the water sample after this two-stage treatment, eco-toxicity tests based on a microbial biosensor (Aliivibrio fischeri) were applied, confirming the high efficiency of the proposed method.

AB  - The corrosion behaviour of three types of alloys (two low-alloy carbon steel and one stainless iron with ~15 wt.% Cr), in a solution which simulates seawater (3% NaCl solution, pH 8.1) was tested. Tested samples are used to make steel (iron) balls applied in mils for grinding copper and other ore. The corrosion tests were performed using three electrochemical methods, at room temperature in the presence of atmospheric oxygen. The linear polarization resistance (LPR) method, electrochemical impedance spectroscopy (EIS) method, and linear sweep voltammetry (LSV) method were applied. Based on measurements by LPR and EIS methods (as non-destructive methods), the value of polarization resistance (Rp) was determined and the general corrosion rate (vcorr) of the examined samples was calculated. The obtained values of the general corrosion rate can be used to calculate the service life of steel (iron) balls under exploitation conditions (seawater). The appearance of the surface after linear sweep voltammetry (LSV) measurement showed the presence of localized corrosion (pits were formed) of the tested samples, especially stainless iron, and the LSV method is not suitable for the determination of the general corrosion rate of tested samples in seawater. This form of corrosion occurs at high anodic polarizations, during performing LSV measurements.

AB  - Organobentonites have been applied for the removal of two common non-steroidal anti-inflammatory drugs, ibuprofen (IBU) and diclofenac sodium (DS), from aqueous solutions. Two surfactants, one with and the other without benzyl group (octadecyldimethylbenzylammonium chloride, ODMBA, and hexadecyltrimethylammonium bromide, HDTMA), in amounts equivalent to 50, 75, and 100% of the cation exchange capacity of bentonite were used for the preparation of organobentonites. Successful modification of bentonite was confirmed by several methods: X-ray powder diffraction (XRPD), point of the zero charge (pHPZC), determination of exchanged inorganic cations in bentonite, determination of textural properties, and scanning electron microscopy (SEM). Kinetic and thermodynamic data on the adsorption of IBU and DS showed that drug adsorption was controlled by the type and the amount of surfactant incorporated into the bentonite and by their arrangement in the interlayer space and at the surface of organobentonites. The adsorption of both drugs increased with an increase in the amount of both surfactants in organobentonites. The presence of the benzyl group in organobentonites enhanced the adsorption of IBU and DS and was more pronounced for IBU. Drug adsorption fits the pseudo-second-order kinetic model the best. The thermodynamic data revealed that the adsorption process was endothermic in nature and with increase of the amount of both surfactants drug adsorption processes were more spontaneous. The results obtained from this study revealed that adsorbents based on surfactants modified bentonite are promising candidates for IBU and DS removal from contaminated water.

AB  - Expanded vermiculite (EVer) was acid activated and silanized in order to obtain suitable substrate’s surface for decoration with iron oxyhydroxides (IO). Obtained activated sample (EVa), was decorated by deposition of either prevailing goethite or amorphous iron oxyhydroxides (AIO) resulting in EV-A and EV-B adsorbent, respectively. Modifications of EVa showed improved adsorption performances when used as adsorbent of lead, chromates and selenites. Adsorption experiments conducted in a batch and column system demonstrated good potential for purification of water contaminated with Pb2+, Cr(VI), and Se(IV). Equilibrium adsorption capacity of EV-A in relation to Pb2+ and Cr(VI) were 48 and 54 mg g-1, respectively, while EV-B showed even better effectiveness for Se(IV) achieving 120 mg g-1 capacity. Regeneration of pollutant saturated adsorbents approved that prepared adsorbents possess fine removal potency even after five adsorption/desorption cycles from 87.58 (for Pb2+/EV-A) to 92.81 % (for Cr(VI)/EV-A) of initial adsorption capacity.

AB  - Cotton-based membranes, due to their exceptional biocompatibility and sustainability,
have attracted considerable attention in various applications, especially in the field of bio and
green technologies. This study investigates the biodegradation potential of cotton membranes
modified with TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) radical and citric acid (CA),
with the aim of improving their properties and facilitating environmentally friendly disposal.
TEMPO radicals, in conjunction with the crosslinker citric acid, are incorporated into the
cellulose structure through a novel modification process. The citric acid component acted as a
plasticizer, increasing the amorphous parts of the cellulose and promoting enzymatic attack.
The TEMPO radical, with its nitroxyl group, contributed to the oxidation of cellulose, further
facilitating biodegradation.
The biodegradation aspect of these modified membranes was investigated in
controlled environmental conditions (Soil Burial test), simulating natural scenarios (humidity,
influence of enzymes, and bacteria). Biodegradation parameters such as weight loss,
structural changes, and degradation kinetics were examined during 90 days. Characterization
of the structure was performed using FTIR and SEM methods.
Our findings suggest that cellulosic membranes possess complete (100%)
biodegradability after 70 days compared to unmodified membranes. Obtained result shed
light on the potential of membranes modified in this way as sustainable and biodegradable
alternatives in various applications. The results emphasize their ecological nature and ability
to reduce environmental stress. Such cellulose-based materials promise a much greener future
in biotechnology, healthcare, and environmental protection.

AB  - This research evaluates the effects of the acid environment on sulfur-polymer composite. For this purpose, a morphology investigation consisting of mathematical morphology analysis and SEM analysis was performed. Based on the obtained results, insignificant changes in the pore system of sulfur-polymer composite in terms of deterioration, pore distribution, and homogeneity were observed. Namely, no signs of severe damage were detected at the surface and inside the samples. With increasing the acid exposure time, the material exhibited further changes in the direction of homogenization and drowning of the aggregate in the sulfur binder compared with the starting structure. These facts indicate that sulfur-polymer composite can be effectively used as a construction material in an acid environment.

AB  - Mechanical activation of materials leads to qualitative changes in material structure. These changes can include the accumulation of energy in the form of weakening bonds in the crystal, disruption of the crystal lattice, agglomeration, and in some cases even the synthesis of a completely new substance. In this study, anhydrous sodium carbonate was mechanically activated for 28 minutes in a vibro mill at a frequency of 3000 oscillations per minute. After activation, the changes occurring in the activated material were monitored. The samples were placed in the atmosphere of air at room conditions for 31 days (relaxation period). It was observed that during the relaxation period moisture and carbon dioxide were absorbed by the activated sodium carbonate in form of hemisorption, forming sodium bicarbonate. The transformation mechanism was monitored by Fourier-transform infrared (FTIR) spectroscopy as a function of relaxation time. Characteristic groups were monitored: CO32-, HCO3- and OH-.

AB  - Concrete is a material that has been used for centuries and is often modified using polymers. In the last fifty years, synthetic polymers have been used for the modification of concrete, but also for the production of concrete. In recent decades, sulfur concrete has been an interesting product that can be used mainly in low-rise construction due to its characteristics. In this work, we used the starting mixture for the preparation of sulfur concrete (sand, elemental sulfur with the addition of modified sulfur and fillers) heated to a temperature of 120 ºC to 170 ºC and homogenized. The results of previous research on the production of sulfur concrete showed that the density of the obtained product changes depending on the type as well as the amount of filler added to the basic mixture based on raw materials. Talc, microsilicon, plate alumina and fly ash were used as fillers. The amounts of fillers were 0%, 1%, 3%, 5%, 7% and 10%.

AB  - Cobalt–chromium–molybdenum (CoCrMo) alloys are known for medical use due to their biocompatibility, corrosion and 
wear resistance. The chemical and phase composition, as well as microstructure of the alloy directly affect the mechanical  properties. In this investigation, CoCrMo alloy samples were obtained by vacuum precise casting. The procedure of  melting and casting process as well as their parameters are given. Molds fabricated of copper, gray iron, steel, ceramics  and graphite were used during the casting process. In this way, the cooling rate influence on the obtained microstructure  was examined. Besides, different casting temperatures (1400°C, 1450°C and 1500°C) were applied for each kind of mold.  After metallographic preparation, the microstructure was examined on the cross section of samples by optical microscopy.  The obtained results show that by increasing the cooling rate, the microstructure of samples become finer and more  homogeneous.

AB  - Nickel pollution of water induces several problems for the environment. The purpose of this paper was to
investigate the adsorption of Ni2+ ions on fabricated biomembranes. The proposed adsorbent was prepared
from epoxy and amino-functionalized waste cellulose fibers, able to participate in cross-linking with amino
acid lysine - wCell/Mn-Fe_LDH. The prepared material underwent preliminary structural characterization
by Fourier-transform infrared spectroscopy. In a batch system, the influence of pH, contact time,
temperature, and initial concentration on adsorption efficiency was investigated. The effectiveness of the
membrane was demonstrated by acceptable adsorption capacities of 40.49 mg g-1 obtained for Ni2+ at 45°C.
The kinetic study, using the Weber-Morris model, indicates intraparticle diffusion as the rate limiting step.
Adsorption mechanism physisorption was proposed based on thermodynamic behaviors. The outcomes
demonstrated that environmentally friendly sustainable technology has been successfully developed.

AB  - The pattern recognition approach, explored by this study, applies the principal component analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation and propagation of the cracks and defects that appear on the surface of material exposed to the cavitation. The experiment was performed in four stages: (a) synthesis of two ceramic materials (cordierite and zircon); (b) subjecting the samples to the cavitation; (c) using image analysis software for collecting the data about morphological characteristics that describe defects; (d) principal component analysis as a pattern recognition tool in order to characterize the defects at the material surface. Besides that, according to standard, cavitation erosion was monitored by determining material mass loss during the cavitation. Large experimental datasets collected from morphological descriptors by image analysis are multivariate and difficult to interpret, thus are processed by principal component analysis as the most informative technique for extracting possible differences. The performed approach proved that this method has a great potential for better assessment of induced defects by proper distinguishing among them at different levels and that can be considered a very efficient and cost-effective one.

AB  - Due to the increasing use and widespread of plastics, poly (ethylene terephthalate) (PET) and poly
(vinyl chloride) (PVC) are becoming one of the major threats to the environment. The aim of this
paper is obtaining plasticizers from recycled PET, and hot/cold mixing thereof with PVC to produce
new materials. Plasticizer was obtained from PET using ethylene glycol (EG) in the presence of
catalyst FASCAT 4100, followed by treatment with maleic anhydride and finally 2-ethylhexanol
(2-EtHex). The obtained glycolysate and plasticizer, individually or mixtures thereof, were used for
the production of polygranulates based on waste PVC in order to obtain an expanded mass of
homogenized PVC with glycolysate/plasticizer. The abovementioned procedures and test results for
the regranulates and products indicate that the proposed technology offers a solution to the problem
of waste PET and PVC through transesterification in order to obtain plasticizer based on PET and
EG, called 2-EtHex/MA/РG/PET/EG/MA/2-EtHex used in the processing of PVC waste and in
regranulate. The obtained regranulates are further processed by injection molding or extrusion into
commercial products such as slippers, footwear, boots, garden hoses, mats, floor mats, etc.

AB  - The mutual interaction of metal ions (lead, zinc and copper) on removal efficiency in binary and ternary systems, by biosorbent based on alkali treated apricot shells (Prunus armeniaca L.) was examined. The evaluation was done in batch system at two metals concentrations: 0.2 and 0.5mmol/ dm3. Tested biosorbent exhibited preferential uptake of lead in a multimetal systems. It is evident that mutual inhibition exists in all multimetal systems, but systems containing lead ex-hibited extreme inhibition toward copper and zinc ions. Process of sorption depends not only on specific chemistry of each metal, their affinity toward binding sites and the type of metal binding onto biosorbent, but also on sorbent chemical and morphological characteristics. In multimetal systems, tested sorbent showed preferential sorption orders: Pb (II)>Cu (II)>Zn (II).

AB  - Infant nutrition is essential for their growth and development. This research aims to determine the total antioxidant capacity of the infant food for preterm infants and indicate adequate methods for testing the quality and biological value of milk and infant food. The total antioxidant capacity (TAC) was determined in human milk and an infant formula for premature infants. The determination of the total antioxidant capacity was made using cyclic and differential pulse voltammetry, potentiometry and electron paramagnetic resonance spectroscopy. The results of three comparative electrochemical methods indicate that human milk has a higher antioxidant potential compared to infant formula, which contributes to better physiological development of the child. Fenton-based electron paramagnetic resonance spectroscopy method provides additional insight into TAC analysis, whereby a carbon-centered radical and an ascorbyl radical are formed in infant food. All methods can be used to determine TAC, since the results obtained individually with each method follow the same trend.

AB  - The aim of this paper is to investigate the application of modified lignin-based adsorbent for
successful removal of dichromate ions and sodium diclofenac (DCF) from aqueous solutions by
adsorption. Modification of lignin-based adsorbent (LBA) was performed by inverse suspension
copolymerization with branched poly (ethylene-imine) using epichlorohydrin as a crosslinker. After
that, the functionalization of LBA was performed by chemical binding of amino modified nanoparticles
of manganese (IV) oxide, in order to improve the adsorption properties. Characterization of
LBA-MnO2 microspheres was performed using FT-IR spectrometer, Scanning electron microscopy,
BET/BJH analysis. The adsorption process was performed in a batch adsorption system. The results
were obtained with the help of kinetic and corresponding equilibrium adsorption isotherms. The
maximum adsorption capacity for the removal of Cr2O7
2- ions and DCF was obtained using the
Langmuir model and amounts to 88.4 mg g-1 and 52.8 mg g-1 at 45 °C, respectively. Adsorption
kinetics was described using a second-order pseudo model. Based on thermodynamic parameters, it
was concluded that the adsorption process is an endothermic and spontaneous. Based on the obtained
results, LBA-MnO2 material possess very good adsorption properties.

Akrilna funkcionalizacija kraft lignina je izvedena direktnom esterifikacijom slobodnih polifenolnih grupa sa akriloil hloridom, nakon čega je AKL umešan u NZP smolu sintetizovanu od poliola dobijenih katalitičkom depolimerizacijom otpadnog poli(etilen tereftalata). AKL je homogenizovan sa NZPS pri različitim masenim udelima: 2,5, 5,0, 7,5 i 12,5 mas.%. Strukturne i dinamičko-mehaničke karakteristike akril-funkcionalizovanog kraft lignina i kompozita određene su primenom FTIR spektroskopije, dinamičkomehaničke analize (DMA) i testova jednoosnog zatezanja. Proučavan je uticaj funkcionalizacije i masenog udela AKL na zatezna i termička svojstva NZPS. Vatrootporna svojstva kompozita su ispitivana prema standardnoj UL-94V metodi, na osnovu koje je kompozit sa 12,5 tež. % akril-funkcionalizovanog lignina dostigao najvišu kategorija toplotno otpornih materijala.
AB  - This paper investigates the using potential of acryl-functionalized kraft lignin (AKL) in reducing the flammability of polymer composites based on recycled unsaturated polyester resins (UPR). Acryl functionalization of kraft lignin was performed by direct esterification of free polyphenolic groups with acryloyl chloride, after what, the AKL was blended in UPR resin synthesized from the polyols obtained by catalytic depolymerization of waste poly(ethylene terephthalate). The AKL was homogenized in UPR resin in different weight ratios: 2.5, 5.0, 7.5, and 12.5 wt.%. Structural and dynamic-mechanical characteristics of acryl-functionalized kraft lignin and composites were determined using FTIR spectroscopy, dynamicmechanical analysis (DMA), and tensile tests. The influence of functionalization and mass fraction of AKL on tensile and thermal properties of UPR resin was studied. The thermal properties of the composite were tested according to the standard UL-94 method, based on which the highest category of heat-resistant materials is a composite with 12.5 wt.% acylfunctionalized lignin.
