Liquid chromatography and liquid chromatography-mass spectrometry analysis of donepezil degradation products / Analiza degradacionih proizvoda donepezila primenom tečne hromatografije i tečne hromatografije-masene spektrometrije
(Association of the Chemical Engineers of Serbia, 2015)
This study describes the investigation of degradation products of donepezil (DP) using a stability-indicating RP-HPLC method for determination of donepezil, which is a centrally acting reversible acetyl cholinesterase ...
Calcium oxide based catalysts for biodiesel production: a review
(Savez hemijskih inženjera, Beograd, 2016)
Vegetable oils are mainly esters of fatty acids and glycerol, which can be converted to fatty acid methyl esters (FAME), also known as biodiesel, by the transesterification reaction with methanol. In order to attain ...
A study of photocatalytic degradation of methomyl and its commercial product lannate-90
(Savez hemijskih inženjera, Beograd, 2020)
Photocatalytic degradation of the carbamate insecticide methomyl and its commercial product Lannate-90 in aqueous suspension of TiO2 and ZnO using an Osram ultra-vitalux lamp (315-400 nm) was investigated. The objective ...
Photodegradation of dimethenamid-p in deionised and ground water
(Savez hemijskih inženjera, Beograd, 2016)
The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals ...
Degradation of nicosulfuron using fenton and fenton-like reactions
(Savez hemijskih inženjera, Beograd, 2018)
Nicosulfuron, a sulfonylurea herbicide, was subjected to different Fenton reactions at pH of a nicosulfuron aqueous solution (pH 5). Usually, the optimal pH for the Fenton reaction is between 3 and 4, but the addition of ...
Pressure drop in packed beds of spherical particles at ambient and elevated air temperatures / Pad pritiska u pakovanom sloju sferičnih čestica na sobnoj i povišenim temperaturama
(Association of the Chemical Engineers of Serbia, 2015)
The aim of this work was the experimental investigation of the particle friction factor for air flow through a packed bed of particles at ambient and elevated temperatures. The experiments were performed by measuring the ...
Friction factor for water flow through packed beds of spherical and non-spherical particles
(Savez hemijskih inženjera, Beograd, 2017)
The aim of this work was the experimental evaluation of different friction factor correlations for water flow through packed beds of spherical and non-spherical particles at ambient temperature. The experiments were performed ...
Heterogeneous kinetics of vegetable oil transesterification at high temperature
(Savez hemijskih inženjera, Beograd, 2016)
Currently, the catalytic efficiency and reusability of the solid base catalysts cannot meet the demand of industrial biodiesel production under low temperature. The purpose of this study is to define the kinetics of ...
Structure and properties of TEMPO-oxidized cotton fibers / Struktura i svojstva TEMPO-oksidisanih vlakana pamuka
(Association of the Chemical Engineers of Serbia, 2012)
In this paper, the influence of the catalytic oxidation using water soluble and stable nitroxyl radical 2,2',6,6'-tetramethylpiperidine-1-oxyl (TEMPO) on the structure and properties of cotton fibers was studied. In ...
Amoxicillin photodegradation by nanocrystalline tio2
(Savez hemijskih inženjera, Beograd, 2017)
Nanocrystalline TiO2, synthesized by sol-gel route and characterized by XRPD, BET and SEM measurements, was applied in the photocatalytic degradation of amoxicillin, using an Osram Ultra-Vitalux (R) lamp as the light source. ...
