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 ...
Simultaneous photodegradation of two textile dyes using TiO2 as a catalyst
(Springer, 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 ...
Adsorption of linear polyethylene and isotactic polypropylene from 1,1,2,2-tetrachloroethane and 1,2,3-trichloropropane on to polar adsorbents
(Chromatographia, 2006)
Linear polyethylene and isotactic polypropylene samples were dissolved in 1,1,2,2-tetrachloroethane or 1,2,3-trichloropropane and injected at 135 degrees C into columns packed with porous particles of hydroxyapatite, ...
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 ...
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 ...
Adsorption of Tiron onto alumina
(Materials Science Forum, 2005)
It has been shown recently that small organic molecules, used as dispersants in the colloidal processing of ceramic powders to adjust the forces between the particles, are quite efficient in preparing aqueous suspensions ...
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 ...
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 ...
