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 ...
An inverse gas chromatography study of the adsorption of organics on nickel- and copper-hexacyanoferrates at zero surface coverage
(Academic Press Inc Elsevier Science, San Diego, 2002)
The surface properties of Ni and Cu hexacyanoferrates were investigated by the inverse gas chromatography method. Retentions of 10 organic compounds were measured at zero surface coverage in the temperature range 80 to 95 ...
Adsorption of phenol and 2,4-dinitrophenol on activated carbon cloth: The influence of sorbent surface acidity and pH
(Taylor & Francis Inc, Philadelphia, 2006)
In this work the effect of the activated carbon cloth surface acidity and pH of the solution on phenols adsorption has been studied. Two phenols, widely different in the terms of their pKa values (phenol and 2,4-dinitrophenol), ...
Inverse gas chromatrography of chromia. Part II. Finite surface coverage / Inverzna gasna hromatografija na hrom(III)-oksidu. Deo II
(Serbian Chemical Society, Belgrade, 2002)
The interactions of n-hexane, benzene, chloroform, and tetrahydrofuran with dried (amorphous) chromia (I) and chromia heated at 1073 K (crystalline) (II), both obtained from a colloidal dispersion, and a commercially ...
Sorption of boric acid and borax by activated carbon impregnated with various compounds
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The separation of boron compounds, boric acid and borax from aqueous solution by activated carbon before and after impregnation with various compounds was studied. A series of activated carbons was prepared from coconut ...
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 ...
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. ...
Nonlinear frequency response functions of a chromatographic column - A critical evaluation of their potential for estimation of single solute adsorption isotherms
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Nonlinear frequency response analysis is applied to study single component adsorption in chromatographic columns. Single component adsorption isotherms can be estimated from local derivatives of the adsorption isotherm at ...
Recycled-wool-based nonwoven material as a sorbent for lead cations
(Wiley, Hoboken, 2003)
The aim of this study was to investigate the sorption properties of a recycled-wool-based nonwoven material for lead cations. To improve sorption properties, the material was treated with low-temperature air plasma and/or ...
