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 ...
Preparation of glass-ceramic in Li2O-Al2O3-GeO2-P2O5 system
(University of Novi Sad, 2013)
The results of preparation and structural characterization of glass-ceramics from the system Li2O-Al2O3-GeO2-P2O5 are shown in this paper. The crystallization behaviour of the selected glass was examined under non-isothermal ...
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 ...
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 ...
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 ...
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), ...
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 ...
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 ...
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 ...
