Photocatalytic degradation of textile dye C.I. reactive orange 16 in TiO2 water suspension by simulated solar light
(Association of the Chemical Engineers of Serbia, 2007)
The photodegradation of C.I. Reactive Orange 16 (RO16), commonly used as a textile dye, was investigated using TiO2 as a catalyst and the sun lamp. The experiments showed that TiO2 and simulated solar light are necessary ...
The rheological properties of wheat dough containing zeolite residue
(Chemical Industry & Chemical Engineering Quarterly, 2020)
The use of natural zeolite - clinoptilolite, to protect wheat grain from storage insects within environmentally-friendly storage techniques can lead to the presence of small amounts of zeolite residues in flour. This study ...
Rheological examination of erythrocyte aggregation in the presence of lipid-based fine particles / Reološko ispitivanje agregacije eritrocita u prisustvu lipidnih čestica
(Association of the Chemical Engineers of Serbia, 2005)
The development of lipid-based fine particles as potential drug carriers requires a detailed investigation of the possible effects of these carriers on the rheological properties of blood. In this study, we investigated ...
Kovats retention index-boiling point relationship of 2-phenyl-2-alkyl-acetonitriles on stationary phases of different polarity / Zavisnost kovačevog retencionog indeksa od temperature ključanja 2-fenil-2-alkilacetonitrila na stacionarnim fazama različite polarnosti
(Association of the Chemical Engineers of Serbia, 2005)
Linear and reciprocial Kovats retention index-boiling point relationships known from the literature were used to study the Kovats retention index-boiling point dependence of 2-phenyl-2-alkylacetonitriles on stationary ...
Nanocomposite powders for new contact materials based on copper and alumina
(Association of the Chemical Engineers of Serbia, 2008)
This paper is a contribution to characterization of Cu-Al2O3 powders with nanostructure designed for the production of dispersion strengthened contact materials. New materials with predetermined properties can be successfully ...
Design and optimization of purification procedure for biodiesel washing
(Association of the Chemical Engineers of Serbia, 2009)
Almost complete methanolysis of triglycerides is usually not enough to fulfil the strict standards of biodiesel quality. A key step in this process is neutralization of alkali (catalyst) followed by the washing procedure ...
The optimization of zinc dialkyldithiocarbamates synthesis and determination of their antioxidant activity
(Association of the Chemical Engineers of Serbia, 2008)
A two-step optimized laboratory synthetic method of zinc dialkyldithiocarbamates is presented. In the course of the first phase, a sodium salt of dialkyldithiocarbamic acid has been synthesized from the dialkylamines, ...
In situ lead stabilization using natural and synthetic apatite
(Savez hemijskih inženjera, Beograd, 2008)
In this work, mineral apatite was investigated for the remediation of lead contamination. Two different apatite minerals were used: synthetic apatite, Ca10(PO4)6(OH)2 (hereafter denoted as HAP) and natural apatite from ...
The analysis of different processes of extraction: yield of extracts obtained from Aloe vera (Aloe barbadensis Miller) and sweet bay (Laurus nobilis L.) and the exergy analysis of applied processes
(Association of the Chemical Engineers of Serbia, 2009)
The present study was aimed to investigate and compare the efficiency of different methods for the isolation extract from a plant material. Extracts from dried leaves of Aloe vera (A. barbadensis Mill.) and Sweet Bay (Laurus ...
Effect of temperature on the physical changes and drying kinetics in plum (Prunus domestica L.) Požegača variety / Uticaj temperature na fizičke promene i kinetiku sušenja šljive (Prunus domestica L.) sorte požegača
(Association of the Chemical Engineers of Serbia, 2011)
In this study, drying kinetics of autochthonous variety Požegača plum was examined in a laboratory dryer at three temperatures. The whole plum fruits, together with the kernels were subjected to the drying process. The ...
