(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
In this paper, the degradation of organophosphorus insecticide (malathion) with chlorine dioxide was investigated. Degradation was studied in deionized water. Optimization of degradation conditions was examined under light ...
Two step sintering of the ZnTiO3 nanopowder
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Metastabile nanopowder ZnTiO3 pressed into cylindrical compacts at 200 MPa was submitted to conventional heating with isothermal holding at 931oC for 10 minutes, 25 minutes and 40 minutes. Same compacts were heated with ...
Bioremediation of complex pollutants from the oil industry containing cobalt and molybdenum catalysts
(Trans Tech Publications Ltd, 2017)
Bioremediation is the process of detoxification or elimination of pollutants using microorganisms with different metabolic capabilities. Biodegradation by natural populations of microorganisms is one of the primary mechanisms ...
Development of a procedure for bioremediation treatment of underground waters and soils polluted by petroleum
(International Institute of Informatics and Systemics, IIIS, 2018)
Crude oil as a raw material, and all its refined products that are used as fuel, is a highly complex mixture of a large number of saturated and aromatic hydrocarbons and various nitrogen, sulphur and oxygen compounds (NSO ...
Possible Mechanism of Pectin-Derived Oligosaccharides Influence on Gut Microbiota / Predloženi mehanizam uticaja oligosaharida dobijenih iz pektina na intestinalnu mikrobiotu
(Belgrade: University of Belgrade, 2018)
We prepared pectin-derived oligosaccharides (apple and citrus) and polygalacturonic acid-derived oligosaccharides, using alkaline hydrolysis by hydrogen peroxide, and analyzed them by Fourier Transform Infrared spectrometry. ...
Distribution of hydrocarbon biomarkers during microbiological biodegradation of oil
(Beograd: Udruženje mikrobioologa Srbije, 2018)
The pollution of the environment by crude oil and its derivatives is a consequence of human activity, that is, the consequence of the extraction, transport, processing and use of oil. Biodegradation is process of removing ...
