AB  - U ovom istraživanju, ispitivana je sposobnost otpadne biomase kao adsorbenta, pri čemu je ovsena slama (OS) odabrana kao polazna sirovina. Da bi se unapredio kapacitet adsorpcije ovog materijala, on je modifikovan sa odabranim dubokim eutektičkim rastvaračem (DES). Radi proširenja mogućnosti primene nakon tretmana sa DES-om, modifikovana ovsena slama (DOS) je imobilisana u kuglice sa alginatom, te je time dobijen IDOS. Efikasnost adsorpcije teških metalnih jona metala iz rastvora bakra testirana je na modifikovanoj (ili imobilisanoj) ovsenoj slami. Maksimalni dobijeni kapaciteti za adsorpciju jona bakra bili su 26.4, 81.4, 124.78 mg/g respektivno. Dobijeni rezultati pokazali su da adsorpcija prati kinetički model pseudo-drugog reda, što implicira da je hemisorpcija za vezivanje jona bakra, odnosno korak koji kontroliše brzinu adsorpcije.

AB  - Untreated industrial effluent is causing alarming levels of water pollution in our modern world. Hydrochars, functional carbonaceous materials obtained during the hydrothermal carbonization of waste biomass, possess a great potential for use in industrial wastewater treatment. Their high reactivity and regenerative properties compensate its deficiency, which is reflected in a small specific surface area. In addition, these materials are amenable to additional functionalization and modification by various chemical treatments. Previous studies have demonstrated that incorporating metals onto the surface of hydrochar or treating it with hydrogen peroxide or alkalis can significantly enhance its adsorption capabilities. This paper provides a brief overview of using hydrochars from various sources as adsorbents for heavy metals. This review aims to assess the impact of material modification on its structural characteristics and sorption capacity.

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  - INTRODUCTION: Following orthopedic surgery, bacterial infection may lead to significant complications related to
inflammation in the peri-implant region, including the potential for implant loosening. To address this concern, the
surface of metallic implants was modified through the application of bioactive and antibacterial coatings, aiming to
mitigate these issues.
EXPERIMENTAL: HAP/PVA/CS/Gent coatings was single-step electrophoretically deposited from four-component
aqueous suspension containing 1 wt.% hydroxyapatite powder (HAP, particles < 200 nm particle size, Sigma-Aldrich),
0.1 wt.% poly(vinyl alcohol) (PVA, medium molecular weight 89 to 98 kDa, 99 % hydrolysed, Sigma-Aldrich), 0.05 wt%
chitosan powder (CS, medium molecular weight, 190 to 310kDa with 75 to 85 % deacetylation degree, Sigma-Aldrich), and
aqueous gentamicin sulfate solution (Gent, concentration 50 mg/ml, Sigma-Aldrich) on titanium plates (Sigma-Aldrich).
Antibacterial activity of HAP/PVA/CS/Gent coating was evaluated against Staphylococcus aureus TL (culture collection-
FTM, University of Belgrade, Serbia) and Escherichia coli ATCC 25922, while kinetics of antibacterial activity was monitored
according to our previously published data [1]. In vitro cytotoxicity assay was performed towards two fibroblast cell lines
of different origin-mouse origin cell line (L929 (ATCC CRL-6364)) and human lung origin cell line (MRC-5 (ATCC CCL-171)) [2].
To evaluate the statistical significance of the biological assay results (antibacterial activity, cytotoxicity and ALP activity),
one-way analysis of variance (ANOVA) followed by a multiple comparisons posthoc test was used.
RESULTS AND DISCUSSION: HAP/PVA/CS/Gent coating exhibited strong antibacterial effect against both S. aureus
and E. coli, especially pronounced against S. aureus, causing bactericidal effect. Cytotoxic effect of HAP/PVA/CS/Gent
coating was not pronounced in investigated MRC-5 and L929 cell lines. MRC-5 fibroblast cells in contact with
HAP/PVA/CS/Gent doubled alkaline phosphatase levels compared to their contact with the control samples
(HAP/PVA/CS), indicating good osteogenic properties.
CONCLUSIONS: Electrophoretically deposited HAP/PVA/CS/Gent bioceramic coatings on titanium, demonstrated
significant potential as implants in orthopedic practice, functioning as drug carriers. Not only do they possess
antibacterial properties, but they also exhibit no adverse effects on living tissue.

AB  - INTRODUCTION: Tissue engineering strives for innovative solutions in addressing challenges associated with
contemporary bone tissue implants. This study focuses on the electrophoretic deposition (EPD) of hydroxyapatite-based
bioceramic composites containing antibacterial agents onto titanium surfaces. Two composite coatings, hydroxyapatite/
chitosan (HAP/CS) and hydroxyapatite/chitosan/gentamicin (HAP/CS/Gent) were developed to combat issues such as
poor adhesion, limited antibacterial potential, limited bioactivity, and potential toxicity of implant materials [1].
EXPERIMENTAL: EPD was performed at constant voltage (5 V, 12 min) on pure Ti plates from aqueous (HAP/CS and
HAP/CS/Gent) suspensions. The uniformity and functionality of the deposited coatings were assessed through
comprehensive physico-chemical characterization using X-ray diffraction (XRD) (Philips PW 1710, Netherlands) and
scanning electron microscopy (SEM, Hitachi S-4700, J) equipped with energy dispersive X-Ray spectroscopy (EDS, X-Max,
Oxford Instruments, UK). Antibacterial activity was evaluated against Staphylococcus aureus TL and Escherichia coli ATCC
25922 by quantitatively monitoring changes in the viable number of bacterial cells in suspension. Cytotoxicity against
MRC-5 and L929 cell lines was investigated using trypan blue dye-exclusion test (DET) and MTT assay for assessing cell
metabolic activity. Statistical significance was determined for antibacterial and cytotoxicity results by one-way analysis
of variance (ANOVA), followed by multiple comparisons post-hoc test.
RESULTS AND DISCUSSION: XRD revealed broadened diffraction maximums corresponding to fine HAP crystallites.
Porous surface with homogeneously distributed spherical HAP agglomerates embedded in wax-like polymers' matrix of
CS was observed for both coatings by SEM. The addition of gentamicin significantly enhanced the antibacterial activity
of the HAP/CS/Gent coating – complete reduction of S. aureus bacterial cells was achieved within 1 h of exposure. MTT
and DET tests indicated low cytotoxicity against MRC-5 and L929 tested cell line for both samples. Slightly decreased
cell percentage viability due to gentamicin presence was observed for HAP/CS/Gent.
CONCLUSIONS: Single-step EPD yielded antibacterial composite coatings with potential for biomedical applications.
HAP/CS/Gent showed successful gentamicin loading, favorable crystalline structure, and strong antibacterial effects.
The presence of fine HAP crystallites yielded a larger surface area, favorable for new bone growth and improved
osseointegration. HAP/CS/Gent exhibited good antibacterial activity against both tested bacteria (especially
pronounced against S. aureus – bactericidal effect), while preserving low cytotoxicity, indicating the high potential for
biomedical applications.

chitosan (HAP/CS) and hydroxyapatite/chitosan/gentamicin (HAP/CS/Gent) were developed to combat issues such as
poor adhesion, limited antibacterial potential, limited bioactivity, and potential toxicity of implant materials [1].
EXPERIMENTAL: EPD was performed at constant voltage (5 V, 12 min) on pure Ti plates from aqueous (HAP/CS and
HAP/CS/Gent) suspensions. The uniformity and functionality of the deposited coatings were assessed through
comprehensive physico-chemical characterization using X-ray diffraction (XRD) (Philips PW 1710, Netherlands) and
scanning electron microscopy (SEM, Hitachi S-4700, J) equipped with energy dispersive X-Ray spectroscopy (EDS, X-Max,
Oxford Instruments, UK). Antibacterial activity was evaluated against Staphylococcus aureus TL and Escherichia coli ATCC
25922 by quantitatively monitoring changes in the viable number of bacterial cells in suspension. Cytotoxicity against
MRC-5 and L929 cell lines was investigated using trypan blue dye-exclusion test (DET) and MTT assay for assessing cell
metabolic activity. Statistical significance was determined for antibacterial and cytotoxicity results by one-way analysis
of variance (ANOVA), followed by multiple comparisons post-hoc test.
RESULTS AND DISCUSSION: XRD revealed broadened diffraction maximums corresponding to fine HAP crystallites.
Porous surface with homogeneously distributed spherical HAP agglomerates embedded in wax-like polymers' matrix of
CS was observed for both coatings by SEM. The addition of gentamicin significantly enhanced the antibacterial activity
of the HAP/CS/Gent coating – complete reduction of S. aureus bacterial cells was achieved within 1 h of exposure. MTT
and DET tests indicated low cytotoxicity against MRC-5 and L929 tested cell line for both samples. Slightly decreased
cell percentage viability due to gentamicin presence was observed for HAP/CS/Gent.
CONCLUSIONS: Single-step EPD yielded antibacterial composite coatings with potential for biomedical applications.
HAP/CS/Gent showed successful gentamicin loading, favorable crystalline structure, and strong antibacterial effects.
The presence of fine HAP crystallites yielded a larger surface area, favorable for new bone growth and improved
osseointegration. HAP/CS/Gent exhibited good antibacterial activity against both tested bacteria (especially
pronounced against S. aureus – bactericidal effect), while preserving low cytotoxicity, indicating the high potential for
biomedical applications.",

AB  - INTRODUCTION: Electrochemical methods were employed for synthesizing composites intended for applications in
medicine as antibacterial coatings on titanium bone implants or as highly efficient antibacterial hydrogels for
accelerated wound healing.
EXPERIMENTAL: Hydroxyapatite-based coatings were single-step electrophoretically deposited from fourcomponent
aqueous suspension containing 1 wt% hydroxyapatite powder (HAP, particles < 200 nm particle size, Sigma-
Aldrich), 0.1 wt% poly(vinyl alcohol) (PVA, medium molecular weight, Sigma-Aldrich), 0.05 wt% chitosan powder (CS,
medium molecular weight, Sigma-Aldrich), and aqueous gentamicin sulfate solution (Gent, concentration 50 mg/ml,
Sigma-Aldrich) on titanium plates (Sigma-Aldrich). Antibacterial activity of HAP/PVA/CS/Gent coating was evaluated
against Staphylococcus aureus TL (culture collection-FTM, University of Belgrade, Serbia) and Escherichia coli ATCC
25922. For poly(vinyl alcohol)/chitosan (PVA/CHI) hydrogel synthesis poly(vinyl alcohol) powder (PVA, Sigma Aldrich,
USA), chitosan powder (CHI, Sigma Aldrich, USA), graphene (Graphene Supermarket, USA), glacial acetic acid (Beta
Hem), silver nitrate (MP Hemija), potassium nitrate (Centrohem, Serbia) were used. For antibacterial properties
evaluation, monobasic and dibasic (Sigma Aldrich, USA) potassium phosphates were used. Cell culture suspensions for
cytotoxicity tests were prepared using MTT tetrazolium salt, EDTA, fetal calf serum and antibiotic-antimycotic solution
(Sigma Aldrich, USA).
RESULTS AND DISCUSSION: Surface modification of titanium with innovative bioactive coatings enhances
biomineralization and reduces post-operation pain and infection risk. Using powerful single-step electrophoretic
deposition (EPD) at a constant voltage we have produced various hydroxyapatite-based composite bioceramic coatings
in combination with polymers (lignin, chitosan), graphene, and antibacterial agents (silver, gentamicin).
Electrochemical methods enable in situ synthesis of AgNPs inside polymer matrices, with the main advantage being
the complete absence of any chemical reducing agents that are often toxic and difficult to remove from the material.
The electrochemical reduction of Ag+ ions is achieved only using electrical current or pure hydrogen gas that is generated
at the cathode in aqueous electrolytes, which allows for obtaining completely green and non-toxic product.
Modifications in the synthesis process also enable the control of AgNPs properties, such as size and concentration.
CONCLUSIONS: Composite antibacterial coatings were obtained on titanium plates using EPD. Strong antibacterial
activity against E. coli and S. aureus was found. Biocompatibility was confirmed using in vitro MTT testing since a noncytotoxic
effect was shown towards healthy human peripheral blood mononuclear cells PBMC, fibroblast cell lines MRC-5
and L929, suggesting high potential for bone tissue engineering and medical applications. Hydrogels composed of physically
cross-linked poly(vinyl alcohol)/chitosan with embedded AgNPs were successfully developed for applications as antibacterial
wound dressings due to their highly favorable properties of silver release, antibacterial activity, and non-toxicity.

AB  - INTRODUCTION: Owing to its similarity to the inorganic part of the natural bone, excellent bioactivity, biocompatibility,
and ability to stimulate the osteoconductive process, synthetic hydroxyapatite (HAP) is very often the material of
choice for biomedical applications. Diverse ions can be found as substitutes within natural bone structures, each playing
a distinct and crucial role in the physiological processes governing the lifecycle of bones [1]. Among them, strontium ion
has a very important role for the acceleration of osteogenesis and the inhibition of osteoclasts activity [2]. Current
research aims to provide physico-chemical characterization of synthesized HAP and strontium substituted HAP (Sr-HAP)
powders obtained by varying strontium concentration (10, 20 and 40 mol.%) in the starting solutions.
EXPERIMENTAL: HAP powder was synthesized by wet chemical precipitation, using aqueous solutions of Ca(NO3)2
4H2O (Merck, p.a.) and (NH4)2HPO4 (Sigma-Aldrich, ≥99 %). By adding NH4OH (CENTROHEM, p.a.), pH value was adjusted
to 10. The obtained precipitate was heated up to 90 °C. The same procedure was followed for Sr-HAP powder syntheses,
by adding Sr(NO3)2 (Sigma-Aldrich ≥99.0 %) and maintaining the (Ca + Sr)/P ratio at 1.67 in the mixed Ca2+/Sr2+ solution.
Synthesized powders were characterised by FTIR spectroscopy (Nicolet IS-10, Thermo Fisher Scientific), XRD analysis
(Philips PW 1710, Philips, The Netherlands), TG analysis (Netzsch STA 449 F5 Jupiter instrument), and FE-SEM analysis
(JSM-7001F, JEOL Ltd, Japan).
RESULTS AND DISCUSSION: FTIR spectra revealed the presence of carbonate-substituted hydroxyapatite in both pure
and Sr-substituted HAP powders. The powders showed a granular, homogeneous morphology without the Sr separation.
XRD analysis revealed that the amount of incorporated Sr in the HAP structure increased with increased Sr concentration
in the starting solutions. Thermal stability of the Sr-HAP powders decreased with increased Sr concentration.
CONCLUSIONS: Physico-chemical characteristics of Sr-HAP powders are directly dependent on Sr ion concentration
in powders.

AB  - Cilj ovog rada bio je prikaz modela fluktuacije azotnih jedinjenja u površinskim vodama usled
akcidentnih situacija. Slučajno ispuštanje jedinjenja azota, konkretno veštačkih đubriva, ima
veoma štetan uticaj na kvalitet vode i vodene ekosisteme. U ovom radu je navedeno nekoliko

AB  - Smelting used to be less efficient; therefore, wastes obtained from historical processing at smelter plants usually contain certain quantities of valuable metals. Upon the extraction of useful metal elements, metallurgical slag can be repurposed as an alternative mineral raw material in the building sector. A case study was conducted, which included an investigation of the physico-chemical, mineralogical, and microstructural properties of Pb–Zn slag found at the historic landfill near the Topilnica Veles smelter in North Macedonia. The slag was sampled using drill holes. The mineralogical and microstructural analysis revealed that Pb–Zn slag is a very complex and inhomogeneous alternative raw material with utilizable levels of metals, specifically Pb (2.3 wt.%), Zn (7.1 wt.%), and Ag (27.5 ppm). Crystalline mineral phases of wurtzite, sphalerite, galena, cerussite, akermanite, wüstite, monticellite, franklinite, and zincite were identified in the analyzed samples. The slag’s matrix consisted of alumino-silicates, amorphous silicates, and mixtures of spinel and silicates. Due to the economic potential of Pb, Zn, and Ag extraction, the first stage of reutilization will be to transform metal concentrates into their collective concentrate, from which the maximum amount of these crucial components can be extracted. This procedure will include combination of gravity concentration and separation techniques. The next step is to assess the Pb–Zn slag’s potential applications in civil engineering, based on its mineralogical and physico-mechanical properties. Alumino-silicates present in Pb–Zn slag, which contain high concentrations of SiO2, Al2O3, CaO, and Fe2O3, are suitable for use in cementitious building composites. The goal of this research is to suggest a solution by which to close the circle of slag’s reutilization in terms of zero waste principles. It is therefore critical to thoroughly investigate the material, the established methods and preparation processes, and the ways of concentrating useful components into commercial products.

AB  - The incombustible portion of coal that remains after burning is known as bottom or fly ash, and it has a detrimental influence on the environment. One of the possible alternatives for reducing the amount of ash deposited in landfills might be the production of useful glass-ceramic from vitrified fly ash. Glass-ceramic was synthesized using fly ash from the thermal power plant "Nikola Tesla" and fluxing additives. Sinter-crystallization of the parent glass resulted in glass ceramics. The glass was created by melting a combination of coal fly ash (CFA), Na2CO3, and CaCO3 at T= 1500 °C and quenching the melt in the air. Glass powders were sintered at temperatures 850 and 900 °C. The resulting glass-ceramics were characterized microstructurally, physically, and mechanically. The cavitation erosion of samples was evaluated. The cavitation rate was 0.015 mg/min for the sample sintered at 850 °C, and 0.0053 mg/min for the sample sintered at 900 °C. The leaching of heavy metals in glass-ceramic samples was determined using the Toxicity Characteristic Leaching Procedure. A low concentration of heavy metals in the leaching solution showed that heavy metals were successfully incorporated in the glass matrix and that obtained glass-ceramics are ecologically safe for usage. Both samples exhibit good resistance to cavitation erosion, suggesting their potential as possible replacements for structural ceramics commonly employed components of hydraulic machinery.

abstract = "The incombustible portion of coal that remains after burning is known as bottom or fly ash, and it has a detrimental influence on the environment. One of the possible alternatives for reducing the amount of ash deposited in landfills might be the production of useful glass-ceramic from vitrified fly ash. Glass-ceramic was synthesized using fly ash from the thermal power plant "Nikola Tesla" and fluxing additives. Sinter-crystallization of the parent glass resulted in glass ceramics. The glass was created by melting a combination of coal fly ash (CFA), Na2CO3, and CaCO3 at T= 1500 °C and quenching the melt in the air. Glass powders were sintered at temperatures 850 and 900 °C. The resulting glass-ceramics were characterized microstructurally, physically, and mechanically. The cavitation erosion of samples was evaluated. The cavitation rate was 0.015 mg/min for the sample sintered at 850 °C, and 0.0053 mg/min for the sample sintered at 900 °C. The leaching of heavy metals in glass-ceramic samples was determined using the Toxicity Characteristic Leaching Procedure. A low concentration of heavy metals in the leaching solution showed that heavy metals were successfully incorporated in the glass matrix and that obtained glass-ceramics are ecologically safe for usage. Both samples exhibit good resistance to cavitation erosion, suggesting their potential as possible replacements for structural ceramics commonly employed components of hydraulic machinery.",

AB  - By maintaining a large number of local pepper genotypes, it is possible to preserve a large number of desirable genes that can be used in different pepper selection programs. The aim of this study was to classify a part  of  the  collection  of  15  genotypes  (11  populations  and  4  varieties  originating  from  autochthonous populations) of peppers originating from Republic of Serbia. Morphological characteristics (weight, length, width,  pericarp  thickness,  color  before  fruit  ripening,  shape  and  number  of  fruit  chambers)  and  10 phytochemical parameters of the fruit (carbohydrates, essential oils, ash, cellulose, beta carotene, potassium, iron, vitamin C, total phenols, antioxidant activity) were studied. Using statistical multivariate techniques (PCA and Cluster analysis), the degree of variation between local populations was assessed and diversity was determined based on the morphological and nutritional characteristics of pepper fruits. Morphological traits were determined using two main components that accounted for 70.3% of the variability. These components accounted for 49.8% of the variation in nutritional traits. The ‘Čokotanka’ population would be suitable for individual selection and reduced divergence within the population, since it has 6 tested traits that resulted in high  diversity  index.  Populations  ‘Stojankina  kletva’,  ‘Lalić’  and  ‘Strižanka’  would  be  suitable  for recombination of genes to improve the properties of individual selection programs for this vegetable species

AB  - This study presents comparison of our recently formulated two compartmental model with General fractional derivative (GFD) and Korsmeyer-Peppas, Makoid-Banakar and Kopcha diffusion models. We have used our GFD
model to study the release of gentamicin in poly (vinylalcohol)/chitosan/gentamicin (PVA/CHI/Gent) hydrogel aimed for wound dressing in medical treatment of deep chronical wounds. The PVA/CHI/Gent hydrogel was prepared by physical cross linking of poly(vinyl alcohol)/chitosan dispersion using freezing-thawing method, and then was swollen for 48 h in gentamicin solution, at 37 °C. Different physico-chemical (FTIR, SEM), mechanical and biological (cytotoxicity, antibacterial activity) properties have been determined. The concentration of released gentamicin was determined
using a high-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS). The ratio between concentration of released gentamicin and initial concentration of gentamicin in the hydrogel was monitored for the
prolonged time period in order to obtain gentamicin release profile. It was proven that our novel diffusion GFD model better fitted with experimental data, and enabled the determination of diffusion coefficient precisely for the entire time period.

AB  - The concept of a bio-based economy has been adopted by many advanced countries around
the world, and thermochemical conversion of waste biomass is recognized as the most effective
approach to achieve this objective. Recent studies indicate that hydrothermal carbonization (HTC)
is a promising method for the conversion of waste biomass towards novel carbonaceous materials
known as hydrochars. This cost-effective and eco-friendly process operates at moderate temperatures
(180–280 ◦C) and uses water as a reaction medium. HTC has been successfully applied to a wide
range of waste materials, including lignocellulose biomass, sewage sludge, algae, and municipal solid
waste, generating desirable carbonaceous products. This review provides an overview of the key
HTC process parameters, as well as the physical and chemical properties of the obtained hydrochar.
It also explores potential applications of produced materials and highlights the modification and
functionalization techniques that can transform these materials into game-changing solutions for a
sustainable future.

AB  - In this study three bentonite clays (bentonite from deposit Beretnica in Republic of Serbia, commercial bentonite and gray
clay from Šipovo deposit in Bosnia and Herzegovina) were investigated as adsorbents of aflatoxin B1 (AFB1). In a single
in vitro AFB1 adsorption experiment, all three bentonites showed high adsorption efficiency for AFB1 at pH 5. The effect
of adsorbent mass on AFB1 adsorption was also studied, with the same initial AFB1 concentration, at pH 3, and it was
shown that toxin adsorption decreased with decreasing amount of each bentonite in suspension. Thermal analysis was
performed in order to determine the structural differences between investigated bentonites. Results showed that gray clay
was trans-vacant bentonite while other two clays were cis-vacant bentonites. Aflatoxin B1 adsorption experiments, at pH

clay from Šipovo deposit in Bosnia and Herzegovina) were investigated as adsorbents of aflatoxin B1 (AFB1). In a single
in vitro AFB1 adsorption experiment, all three bentonites showed high adsorption efficiency for AFB1 at pH 5. The effect
of adsorbent mass on AFB1 adsorption was also studied, with the same initial AFB1 concentration, at pH 3, and it was
shown that toxin adsorption decreased with decreasing amount of each bentonite in suspension. Thermal analysis was
performed in order to determine the structural differences between investigated bentonites. Results showed that gray clay
was trans-vacant bentonite while other two clays were cis-vacant bentonites. Aflatoxin B1 adsorption experiments, at pH
3, showed that trans-vacant gray bentonite had higher affinity for AFB1 than commercial cis-vacant bentonite. The

AB  - In this study bentonite was modified with two chitosans, commercial or chitosan synthesized from mushroom. Obtained
products were subsequently treated with hexadecyltrimethyl ammonium bromide in the amount of 50% of the bentonite`s
CEC value. Starting material and all prepared composites were characterized by FTIR-ATR spectroscopy in order to
confirm modification with organic molecules. Adsorption of zearalenone (ZEN) by clay-chitosan composites and claychitosan-surfactant composites was investigated at pH 3. Results showed that adsorption of ZEN was higher for
composites that had both chitosan and surfactant, confirming that surfactant ions are responsible for ZEN adsorption.
Additionally, the effect of adsorbent mass on ZEN adsorption was investigated for clay-chitosan-surfactant composites
(pH 3) and results have shown that adsorption increased with increasing the amount of both composites.

AB  - Numerous chemical compounds present in natural waters and wastewater are resistant to
conventional water treatments and persist in treated effluents. Among these substances,
pharmaceuticals, due to their widespread use, raise special concern due to their potentially
harmful effects on human health especially when they reach drinking water. One of the most
efficient technique for removal of pharmaceuticals from polluted water is their adsorption on
various adsorbents, such as activated carbons, clays (kaolin, bentonite, etc.) and zeolites. In
this study, the potential of modified bentonite for removal of carbamazepine, a
pharmaceutical with anticonvulsant and mood-stabilizing properties, was investigated. The
natural bentonite from Šipovo deposit, Bosnia and Herzegovina, was modified with the
cationic surfactant Arquad®2HT-75 in amounts equivalent to 50% and 100% of the
bentonite's cationic exchange capacity. Characterization of prepared samples by Fouriertransform
infrared spectroscopy and Simultaneous Thermal Analysis, confirmed presence of
surfactant in modified bentonites. Results on carbamazepine removal by modified bentonites
showed that its adsorption increased with increasing of the amount of surfactant as well as
with increasing of the initial pharmaceutical concentration. The highest adsorption of
carbamazepine was achieved with bentonite containing the highest amount of surfactant.
Since the natural bentonite has no affinity to remove carbamazepine, these findings suggest
that modified bentonite is a promising adsorbent for its removal from contaminated water.

AB  - In this study, iron oxide nanoparticles immobilized within alginate gel exhibited promising potential for the removal of arsenic (V) ions. The preparation of the polymer-oxide composite  was achieved by the ionic crosslinking of an alginate/iron oxide solution with a calcium (II)ions solution. The maximum amount of arsenic adsorbed by the investigated composite under the experimental conditions was slightly above 26 mg/g in 120 min. The results indicated that arsenic adsorption by this composite material follows a fast kinetic profile, adhering to a pseudo-second-order model. The adsorption process occurs in multiple stages, as suggested by the Weber-Morris model, with external diffusion dominating initially, followed by intraparticle diffusion. Importantly, the results confirmed that the use of alginate gel does not significantly impact the adsorption process, preserving the adsorption capacity of the metal oxides. Overall, the investigated composite successfully removed arsenic (V) from the solution, addressing a critical issue in water treatment.

AB  - Potassium and ammonium salts are necessary to meet the nutritional needs of crops. While the granulation of these materials has traditionally been done by roller compaction, the demand for a rounder and less angular product has led some fertilizer manufacturers to introduce an additional production line to their operations: pelletization (wet granulation) with a disc pelletizer.

AB  - The removal of organic and inorganic sulfur from the Bogovina Basin subbituminous coal by
electrochemical redox reactions was performed. The effect of presence of active bromine species
on the desulfurization process was monitored. The desulfurization was performed in inorganic
acidic solutions that contained different bromide concentrations and in pure acid solution. To
determine the optimal conditions for the desulfurization process, polarization curves were
recorded in three different electrolytes: 0.1 M H2SO4, 0.1 M H2SO4 + 0.01 M KBr, and 0.1 M
H2SO4 + 0.1 M KBr using graphite and dimensionally stable anode (DSA) electrodes as the
anode, while in all cases stainless steel S31603 electrode was used as cathode. By analyzing the
results obtained from the polarization curves, 0.1 M H2SO4 and 0.1 M H2SO4 + 0.1 M KBr were
chosen as the most suitable electrolytes. Also, it was found that the DSA anode showed better
results in terms of energy efficiency of the process compared to the graphite anode and therefore
it was selected for the coal desulfurization process. It is considered that finely suspended coal
particles in an electrolyte can behave according to bipolar electrochemistry. Coal was treated
for 4 hours in two selected electrolytes. The suspension was sampled at different times up to 240
min from the beginning of the process. Sulfur content in coal was determined by elemental
analysis. The results showed that the sulfur content decreases faster in the case of the electrolyte
containing KBr, i.e. that the desulfurization effect is significantly better than in the case of the
system containing only H2SO4. It can be concluded that active bromine species accelerate the
desulfurization process and thus improve energy efficiency.
