(Savez inženjera i tehničara Srbije, Beograd, 2018)
The subject of this study is the quantitative adhesion of a UV-curing composite film based on Bis-GMA (Bisphenol A glycidylmethacrylate) / TEGDMA (triethylene glycol dimethacrylate) as a matrix and particles doped with ...
Sorption of textile dyes from textile wastewater by chitosan-based hydrogel / Sorpcija boja za tekstil iz tekstilnih otpadnih voda pomoću hidrogela na bazi hitozana
(Savez inženjera i tehničara Srbije, Beograd, 2018)
With the excessive risks that are present in today's environment, it is of great importance to treat wastewaters before their discharge in water streams. One of the everyday challenges is design of a low-cost and environmentally ...
Application of raw volcanic rock found in etna valley as an adsorbent of chromates, arsenates and selenates
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with ...
Electrochemical behaviour of sildenafil citrate at gold and cystein modified gold electrode in acid solution
(Int Assoc Physical Chemists-Iapc, Zagreb, 2018)
Electrochemical behavior of sildenafil citrate (SC) at gold and cystein (Cys) modified gold electrode (AulCys) in 0.1 M H2SO4 was investigated by cyclic voltammetry (CV) and by square wave voltammetry (SWV). Effect of scan ...
