Oxidized and Ethylenediamine-Functionalized Multi-Walled Carbon Nanotubes for the Separation of Low Concentration Arsenate from Water
(Taylor & Francis Inc, Philadelphia, 2013)
In this work multiwalled carbon nanotubes (MWCNTs) modified by oxidation (o-MWCNTs) and by aminofunctionalization (e-MWCNTs) were examined as potential adsorbents for arsenate removal from water. Adsorption characteristics ...
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 ...
Hydrogels reinforced with nanoclays with improved response rate
(Wiley-Blackwell, Hoboken, 2017)
Two series of semiinterpenetrating networks (SIPN) based on linear hydrophilic poly(vinyl alcohol) (PVA) and thermoresponsive poly(N-isopropylacrylamide) (PNIPA), physically crosslinked with inorganic clay, are presented. ...
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 ...
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 ...
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 ...

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 ...
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 ...
