The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides / Uticaj rastvarača i strukture na elektronske absorpcione spektre izomernih piridin-karboksilnih kiselina N-oksida
(Association of the Chemical Engineers of Serbia, 2013)
The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen ...
The possibility of application of zeolyte powders for the construction of membranes for carbon dioxide separation
(Savez hemijskih inženjera, Beograd, 2015)
The aim of this study was to construct a polymer-based mixed matrix membrane that could be used for waste gases treatment. Therefore, high permeability for the carbon dioxide and low permeability for other gases commonly ...
A comparative study of the removal of lead, cadmium and zinc ions from aqueous solutions by natural and Fe(III)-modified zeolite / Uporedna analiza uklanjanja jona olova, kadmijuma i cinka iz vodenih rastvora adsorpcijom na prirodnom i Fe(III)- modifikovanom zeolitu
(Association of the Chemical Engineers of Serbia, 2014)
The main purpose of this research was to explain the differences in the adsorption mechanisms and adsorption capacities of natural and Fe(III)-modified zeolite for Pb2+, Zn2+ and Cd2+. The adsorbents were characterized ...
Kinetics of heterogeneous methanolysis of sunflower oil with CaO·ZnO catalyst: Influence of different hydrodynamic conditions / Kinetika heterogene metanolize suncokretovog ulja sa CaO·ZnO kao katalizatorom - uticaj različitih hidrodinamičkih uslova
(Association of the Chemical Engineers of Serbia, 2014)
The kinetics of heterogeneous methanolysis of sunflower oil was studied at 60 °C using mechanochemically synthesized CaO·ZnO as catalyst. The influence of agitation speed, catalyst amount, and methanol-to-oil molar ratio ...
Viscosities and refractive indices of binary systems acetone+1-propanol, acetone+1,2-propanediol and acetone+1,3-propanediol / Viskoznosti i indeksi prelamanja binarnih sistema aceton+1-propanol, aceton+1,2-propandiol i aceton+ 1,3-propandiol
(Association of the Chemical Engineers of Serbia, 2014)
Viscosities and refractive indices of three binary systems, acetone+1-propanol, acetone+1,2-propanediol and acetone+1,3-propanediol, were measured at eight temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, ...
Investigation of forced and total degradation products of amlodipine besylate by liquid chromatography and liquid chromatography-mass spectrometry / Ispitivanje degradacionih proizvoda amlodipin-bezilata primenom tečne hromatografije i tečne hromatografije-masene spektrometrije u uslovima forsirane i potpune degradacije
(Association of the Chemical Engineers of Serbia, 2014)
An isocratic, reversed-phase liquid chromatographic method was applied for the investigation of the degradation products of amlodipine besylate under stressed conditions in solution. Amlodipine besylate stock solutions ...
