Novel negatively charged membrane adsorbers made using a combination of photopolymerization and immersion precipitation
(Srpsko hemijsko društvo, Beograd, 2016)
A novel method combining a traditional immersion precipitation process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution was used to prepare asymmetric ...
Transport properties of binary liquid mixtures - Candidate solvents for optimized flue gas cleaning processes
(Srpsko hemijsko društvo, Beograd, 2016)
Thermal conductivities and viscosities of three pure chemicals, monoethanolamine (MEA), tetraethylene glycol dimethyl ether (TEGDME) and polyethylene glycol 200 (PEG 200) and two binary mixtures (MEA++TEGDME and MEA+ PEG ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
PVB/sepiolite nanocomposites as reinforcement agents for paper
(Srpsko hemijsko društvo, Beograd, 2016)
In order to improve the mechanical properties of paper, 1, 3 and 5 wt. % of sepiolite were dispersed in a poly(vinyl butyral) (PVB) matrix and coated onto the surface of schrenz (110 g m(-2)). Deagglomerated sepiolite ...
Solvatochromism of isatin based Schiff bases: An LSER and LFER study
(Srpsko hemijsko društvo, Beograd, 2016)
The derivatives of isatin (1H-indole-2,3-dione) have already been reported to show a variety of biological activities. However, there have hitherto been no reports on the solvatochromic effects of isatin derivatives, and ...
Efficient pollutants removal by amino-modified nanocellulose impregnated with iron oxide
(Srpsko hemijsko društvo, Beograd, 2016)
A novel adsorbent, NC-PEG, obtained by modification of nanocellulose (NC) with PEG-6-arm amino polyethylene glycol (PEG-NH2) via maleic anhydride (MA) linker, was used for removal of Cd2+ and Ni2+ from water. A subsequent ...
Sepiolite functionalized with N-[3-( trimethoxysilyl)propyl]-ethylenediamine triacetic acid trisodium salt. Part II: Sorption of Ni2+ from aqueous solutions
(Srpsko hemijsko društvo, Beograd, 2016)
The sorption of Ni2+ on sepiolite functionalized by covalent grafting of N-[3-(trimethoxysilyl) propyl] ethylenediamine triacetic acid trisodium salt, MSEAS, was studied in batch experiments as a function of the initial ...
A study of the barrier properties of polyethylene coated with a nanocellulose/magnetite composite film
(Srpsko hemijsko društvo, Beograd, 2016)
The morphological, thermal and barrier properties of low-density polyethylene/polycaprolactone-modified nanocellulose hybrid materials were investigated in this study. Nanocellulose/magnetite (NC-Fe3O4) nanocomposite and ...
Relationship between the kinetic parameters and morphology of electrochemically deposited lead
(Serbian Chemical Society, 2016)
The processes of lead electrodeposition from electrolytes of various concentrations of sodium nitrate as the supporting electrolyte have been examined by chronoamperometry and by the scanning electron microscopic (SEM) ...
Investigation of different extraction procedures for the determination of major and trace elements in coal by ICP-AES and ion chromatography
(Srpsko hemijsko društvo, Beograd, 2016)
This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different ...
