Removal of metal cations from wastewater using recycled wool-based non-woven material / Uklanjanje katjona metala iz otpadne vode netkanim materijalom na bazi vune kao sekundarne sirovine
(Serbian Chemical Society, Belgrade, 2007)
In this study, the effect of low-temperature air plasma, biopolymer chitosan and hydrogen peroxide treatment of recycled wool-based non-woven material on metal cation uptake was investigated. Recycled wool-based material ...
Immobilized lipases as practical catalysts / Imobilisane lipaze kao katalizatori
(Srpsko hemijsko društvo, Beograd, 2006)
Attractive features of lipase systems include versatility, substrate selectivity, regioselectivity, enantioselectivity and catalysis at ambient temperatures and pressures. To fully exploit the technical and economical ...
Inverse gas chromatography of chromia, Part I: Zero surface coverage / Inverzna gasna hromatografija hromoksida, Deo I - nulta površinska pokrivenost
(Serbian Chemical Society, Belgrade, 2001)
The surface properties of the solid obtained from colloidal chromia were investigated by inverse gas chromatography (IGC), at zero surface coverage conditions. The solid samples I dried at 423 K and II heated at 1073 K in ...
Influence of different carbon monolith preparation parameters on pesticide adsorption / Uticaj parametara dobijanja karbon monolita na adsorpciju pesticida
(Serbian Chemical Society, Belgrade, 2013)
The capacity of carbon monolith for pesticide removal from water, and the mechanism of pesticide interaction with the carbon surface were examined. Different carbon monolith samples were obtained by varying the carbonization ...
The adsorption of imidacloprid onto activated carbon obtained by carbonization of pine cones / Adsorpcija imidakloprida na aktivnom uglju dobijenom karbonizacijom borove šišarke
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
Pine cones of European Black pine are utilized as a precursor for obtaining powdered activated carbon. The concentrated phosphoric acid was used as an activating agent. A detailed study of the imidacloprid adsorption onto ...
Functionalization of thermo-acid activated sepiolite by amine-silane and mercapto-silane for chromium(VI) adsorption from aqueous solutions / Adsorpcija hroma(VI) iz vodenih rastvora na termo-kiselinski aktiviranom sepiolitu funkcionalizovanom amino-silanom i merkapto-silanom
(Association of Chemical Engineers of Serbia, 2013)
Chromium(VI) adsorption from aqueous solutions onto thermo-acid activated sepiolite functionalized with (3-mercaptopropyl)trimethoxy-silane and [3-(2-aminoethylamino)propyl]trimethoxy-silane was investigated. Scanning ...
Removal of organochlorine pesticides from water using virgin and regenerated granular activated carbon / Uklanjanje pesticida iz vode na granulisanom aktivnom uglju
(Serbian Chemical Society, Belgrade, 2010)
Public water systems use granular activated carbon in order to eliminate pesticides. After saturation, the used activated carbon is regenerated and reused in order to reduce the costs of water production and minimize waste. ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
Removal of a cationic dye from water by activated pinecones
(Srpsko hemijsko društvo, Beograd, 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 ...
Analytical methods for arsenic speciation analysis / Analitičke metode za analizu arsenovih jedinjenja
(Serbian Chemical Society, Belgrade, 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, ...
