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 ...
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 ...
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 ...
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. ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2007)
The adsorption mechanisms of Ph2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge pH(pzc), is 7.4 +/- 0.1 for ...
Adsorption of itaconic acid from aqueous solutions onto alumina / Adsorpcija itakonske kiseline iz vodenih rastvora na aluminijum-oksidu
(Serbian Chemical Society, Belgrade, 2008)
Itaconic acid, IA (C5H6O4), was investigated as a potential flocculant for the aqueous processing of alumina powders. The adsorption of IA, as a function of its concentration and pH value of the solution, onto the alumina ...
Surface characterization of macroporous glycidyl methacrylate based copolymers by inverse gas chromatography
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, with different porosity parameters were synthesized by suspension copolymerization and modified by ring-opening ...
Applications of non-linear frequency response for investigation of adsorption systems
(Soc Chemists Technologists Madeconia, Skopje, 2009)
Two main directions of application of nonlinear frequency response and the concept of higher order frequency response functions (FRFs) in investigation of adsorption systems are presented, one for development of novel ...
