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  - Pollution of water with toxic substances is increased. Therefore, innovative solutions
for their treatment are essential. This paper represents results from an adsorption study where
novel synthesized biobased membranes were applied in the removal of dye metanil yellow
from wastewater solution. Batch adsorption tests were applied, where the different
operational impacts including contact time, initial pollutant concentration, temperature, etc.
were varied. Fabricated membranes were based on waste cellulose tobacco boxes modified
by amino acid lysine with an aim to increase sorption capacity toward azo dye. Structural
properties were examined by FE-SEM and ATR-FTIR techniques. The activities of materials
prior to and after modification were compared. It was found that the modified material
achieved a better sorption capacity. The resulting adsorption capacity for the improved
membrane was 65 mg/l compared to 51 mg/l, at 45°C, for the base cellulose membrane. The
kinetics of the process follows a pseudo second-order curve. The best agreement of the
correlation factor R2 was shown with the Freundlich isotherm. The obtained results show the
success of the modification with a good sorption capacity of the material towards the target
pollutant. Overall, it can be concluded that the modified membranes lay a good foundation
for potential application in industrial dye wastewater treatment systems.

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  - 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).
