Impact of different concentrations of alginate in alginate-yeast hydrogel biosorbent
(Savez hemijskih inženjera Srbije, 2024)
Dyeing industry wastewater is one of the major environmental problems.Biosorption technology is regarded to be inexpensive and ecologically beneficial. Spent brewery yeastused in this researchis proposed as ...
Waste cotton polyester yarn as an adsorbent for the removal of heavy metals from wastewater
(Society of Physical Chemists of Serbia, 2021)
Waste cotton/polyester yarn was used for the removal of Pb(II), Cd(II), Cr(III) and As(V) ions from aqueous solution. In attempt to increase the adsorption efficiency, cotton/polyester yarn was modified by sodium hydroxide ...
A Strategy to Revalue a Wood Waste for Simultaneous Cadmium Removal and Wastewater Disinfection
(Adsorption Science & Technology, 2021)
In this investigation, the possibility of wood waste (hardwoods such as oaks' and alternatives' staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All ...

(Beograd : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS), Society for Renewable Electrical Power Sources, 2023)
This paper present the results of defining the mathematical model which describes the dependence
of tensile strength from the influential input parameters, aimed at developing non-toxic alloys that
could completely respond ...
DEALLOYING OF PdNi5 ALLOY IN 0.5M SULFURIC ACID / DEALLOYING PdNi5 LEGURE U 0.5M SULFATNOJ KISELINI
(Beograd : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS), Society for Renewable Electrical Power Sources, 2023)
Palladium alloys with low nickel content are commonly used as catalyst-trap for platinum or
platinum-rhodium catalysts in the process of production of nitric acid. Pure palladium and,
consequently, alloys with a high ...
PHYSICO-CHEMICAL CHARACTERIZATION OF PCBs / FIZIČKO-HEMIJSKA KARAKTERIZACIJA ŠTAMPANIH PLOČA
(Beograd : Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS), Society for Renewable Electrical Power Sources, 2023)
Recycling of printed circuit boards (PCBs) is an extremely complex and sensitive process. Physicochemical
characterization of printed circuit boards is significant for choosing the optimal
processing procedure. The aim ...
Chitosan Nanoparticles Functionalized Viscose Fabrics as Potentially Durable Antibacterial Medical Textiles
(Materials, 2021)
This research proposed two pretreatments of viscose fabrics: oxidation with 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) and coating with TEMPO-oxidized cellulose nanofibrils (TOCN), to introduce functional groups ...
