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 ...
Microwave-assisted hydrodistillation of juniper berry essential oil: kinetic modeling and chemical composition
(Wiley, Hoboken, 2016)
BACKGROUNDMicrowave-assisted hydrodistillation (MAHD) has widely been used to isolate essential oil from various plant materials, but it has not been applied yet to extract essential oil from juniper berries. The main goals ...
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 ...
Enzymatic decolorization of anthraquinone dyes from wastewaters / Enzimsko obezbojavanje antrahinonskih boja iz otpadnih voda

Lead(ii) removal from aqueous solutions by Serbian zeolitic tuff
(Gheorghe Asachi Technical University of Iasi, Romania, 2017)
The present study was aimed at examining the ability of the natural zeolitic tuff from the Zlatokop deposit in Serbia to remove Pb(II) ions from aqueous solutions under various conditions. It has been found that the ...
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. ...
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 ...
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 ...
High temperature transesterification of soybean oil with methanol using manganese carbonate as catalyst
(Savez hemijskih inženjera, Beograd, 2018)
