Photodegradation of dimethenamid-p in deionised and ground water
(Savez hemijskih inženjera, Beograd, 2016)
The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals ...
Pressure drop in packed beds of spherical particles at ambient and elevated air temperatures / Pad pritiska u pakovanom sloju sferičnih čestica na sobnoj i povišenim temperaturama
(Association of the Chemical Engineers of Serbia, 2015)
The aim of this work was the experimental investigation of the particle friction factor for air flow through a packed bed of particles at ambient and elevated temperatures. The experiments were performed by measuring the ...
Challenges in bioethanol production: utilization of cotton fabrics as a feedstock
(Savez hemijskih inženjera, Beograd, 2016)
Bioethanol as a dean and renewable fuel with its major environmental benefits, represents a promising biofuel today which is mostly used in combination with gasoline. It can be produced from different kinds of renewable ...
Effect of la2o3 on the structure and the properties of strontium borate glasses
(Savez hemijskih inženjera, Beograd, 2016)
The selected lanthanum-strontium borate glasses were prepared by a conventional melt-quenching technique. The compositions of the investigated glasses were chosen to be: 5.7, 9.5, 14.3, 19.1 mol% for La2O3, 22.9, 19.1, ...
Influence of monomer and crosslinker molar ratio on the swelling behaviour of thermosensitive hydrogels / Uticaj molarnog odnosa monomera i umreživača na karakteristike bubrenja termoosetljivih hidrogelova
(Association of the Chemical Engineers of Serbia, 2012)
The synthesis of the poly(N-isopropylacrylamide-co-2-hydroxypropyl-methacrylate) hydrogel along with the analysis of the residual monomers content and influence of monomer and crosslinker molar ratios on the swelling ...
Amoxicillin photodegradation by nanocrystalline tio2
(Savez hemijskih inženjera, Beograd, 2017)
Nanocrystalline TiO2, synthesized by sol-gel route and characterized by XRPD, BET and SEM measurements, was applied in the photocatalytic degradation of amoxicillin, using an Osram Ultra-Vitalux (R) lamp as the light source. ...
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 ...
Photocatalytic degradation of textile dye CI Basic Yellow 28 in water by UV-A/TiO2
(Association of the Chemical Engineers of Serbia, 2007)
CI Basic Yellow 28 (BY28), commonly used as a textile dye, could be photocatalytically degraded using TiO2 as catalyst and irradiated by UV-A lamp (300 W). However, UV and TiO2 showed no effect on the photodegradation when ...
