Natural Diatomite (Rudovci, Serbia) as Adsorbent for Removal Cs from Radioactive Waste Liquids
(Science of Sintering, 2015)
The removal of Cs (I) ions from aqueous solution was studied using natural diatomite as adsorption materials originated from Rudovci, Serbia. The microstructure of natural diatomite has been characterized by X-ray diffraction ...
Simultaneous photodegradation of two textile dyes using TiO2 as a catalyst
(Reaction Kinetics, Mechanisms and Catalysis, 2016)
The simultaneous photocatalytic degradation of two dyes: methylene blue (MB), a cationic dye, and arylazo pyridone dye (SD), an anionic dye was investigated using sol-gel prepared TiO2 particles. The paper shows the main ...
Deposition of hematite particles on alumina seal faceplates of nuclear reactor coolant pumps - laboratory experiments and industrial feedback
(Hemijska industrija, 2012)
In the primary circuit of pressurized water reactors (PWR), the dynamic sealing system in reactor coolant pumps is ensured by mechanical seals whose ceramic parts are in contact with the cooling solution. During the ...
Cesium Removal from Aqueous Solution By Natural Mineral Clinoptilolite
(Nuclear technology and radiation protection, 2014)
The aim of this study was to investigate the Cs+ ions sorption on natural minerals clinoptilolite. The analysis of clinoptilolite and clinoptilolite with adsorbed Cs+ ion was conducted by X-ray diffraction, scanning electron ...
Adsorption of azo dyes on polymer materials
(Hemijska industrija, 2013)
The use of polymeric adsorbents for the removal of azo dyes from solution has been reviewed. Adsorption techniques are widely used to remove certain classes of pollutants from waters, especially those which are not easily ...
Ab Initio Study of Graphene Interaction with O-2, O, and O-
(Macedonian Journal of Chemistry and Chemical Engineering, 2016)
A systematic ab initio (DFT-GGA) study of adsorption of various oxygen species on graphene has been performed in order to find out general trends and provide a good starting point to analyze the oxidation of more complex ...
Analytical methods for arsenic speciation analysis
(Journal of the Serbian Chemical Society, 2013)
Arsenic exists in the form of various chemical species differing in their physicochemical behaviour, toxicity, bioavailability and biotransformation. The determination of arsenic species is an important issue for environmental, ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Journal of the Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
Influence of chemical agents on the surface area and porosity of active carbon hollow fibers
(Journal of the Serbian Chemical Society, 2011)
Active carbon hollow fibers were prepared from regenerated polysulfone hollow fibers by chemical activation using: disodium hydrogen phosphate 2-hydrate, disodium tetraborate 10-hydrate, hydrogen peroxide, and diammonium ...
Removal of a cationic dye from water by activated pinecones
(Journal of the Serbian Chemical Society, 2012)
Adsorption of a cationic phenothyazine dye, Methylene Blue onto activated carbon prepared from pinecones was investigated. The parameters contact time, dye concentration and pH were varied. The kinetic data were found to ...
