Enzymatic decolorization of anthraquinone dyes from wastewaters / Enzimsko obezbojavanje antrahinonskih boja iz otpadnih voda
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
Osnovni predmet istraţivanja u okviru ove doktorske disertacije je mogućnost primene peroksidaze iz rena, komercijalnog i neprečišćenog preparata, u obezbojavanju sintetičkih, antrahinonskih boja. Strukturno, ova doktorska ...
Photocatalytic degradation of carbamate insecticides: Effect of different parameters / Fotokatalitička degradacija karbamatnih insekticida - efekti različitih parametara
(Institute of Pesticides and Environmental Protection, 2019)
Photocatalytic degradation of a model compound of the carbamate insecticide carbofuran in water was studied using polychromatic light and ZnO and TiO2 catalysts. The influence of operational parameters, such as reaction ...
Synthesis of liposoluble carboxylic acid ascorbyl esters catalyzed by immobilized lipases / Sinteza liposolubilnih askorbil-estara karboksilnih kiselina katalizovana imobilisanim lipazama
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2016)
In this thesis, possibility of efficient and economical production of carboxylic acid ascorbyl esters catalyzed by immobilized lipases was examined. Vast number of lipases, acyl donors, and organic solvents was tested. ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Srpsko hemijsko društvo, Beograd, 2018)
The MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99-1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
Study of the mechanisms of heavy metal sorption by mineral apatite: the feasibility of soil and ground water remediation / Izučavanje mehanizama sorpcije teških metala apatitom : mogućnost primene u remedijaciji zagađenog zemljišta i podzemnih voda
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2010)
In this work, the mechanisms of heavy metal sorption by two forms of mineral apatite were studied. The materials used include synthetic hydroxyapatite (HAP) and natural apatite from Lisina ore deposit (LA). The materials ...
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 ...
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 ...
Kinetics of heterogeneous methanolysis of sunflower and used vegetable oil / Kinetika heterogene metanolize svežeg i korišćenog biljnog ulja
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2015)
The synthesis of fatty acid methyl esters (FAME), i.e. biodiesel, in the methanolysis of triglycerides (TG) in the presence of solid catalyst was studied. Heterogeneous catalyst was synthesized by mechanochemical treatment ...
High temperature transesterification of soybean oil with methanol using manganese carbonate as catalyst
(Savez hemijskih inženjera, Beograd, 2018)
The manganese carbonate catalyst, prepared by precipitation method, was used in transesterification of soybean oil under subcritical condition of methanol. Catalyst samples were characterized by X-ray diffraction (XRD), ...
The effect of K2O on the crystallization of niobium germanate glasses
(International Institute for the Science of Sintering, Beograd, 2011)
The effect of K2O content on the crystallization of niobium germanate glasses with 22.7- 24.27 wt% of GeO2 and 54.59-57.48 wt% of Nb2O5 was examined. The glasses crystallize by primary crystallization and the formed ...
