Inverse gas chromatography of chromia. Part II. Finite surface coverage
(Journal of the Serbian Chemical Society, 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 ...
Inverse gas chromatography of chromia. Part I. Zero surface coverage
(Journal of the Serbian Chemical Society, 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 healed at 1073 K in ...
A consideration of the correct calculation of thermodynamic parameters of adsorption
(Journal of the Serbian Chemical Society, 2007)
The Langmuir and Freundlich isotherm equations have been widely used for interpreting various adsorption processes. There are, however, many serious mistakes in the literature in determination or calculation of thermodynamic ...
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 ...
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, ...
The effect of gamma radiation on the properties of activated carbon cloth
(Journal of the Serbian Chemical Society, 2009)
Activated carbon cloth dressing is an appropriate wound healing material due to its biocompatibility and adsorption characteristics. The influence of gamma radiation as a sterilization process on the adsorption and mechanical ...
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 ...
Adsorption of itaconic acid from aqueous solutions onto alumina
(Journal of the Serbian Chemical Society, 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 ...
Influence of different carbon monolith preparation parameters on pesticide adsorption
(Journal of the Serbian Chemical Society, 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 ...
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 ...
