Cleaning of Contaminated Waters Against U and Cr Compounds Using Pillared Al- and Al/Fe-Clays

In this paper a comprehensive study of adsorption properties of modified clay minerals with polyoxocomplexes (POM) of iron and aluminium with regard to removal of heavy metal ions from an aqueous medium was carried out. To determine changes in structure characteristics of the intercalated minerals have been used methods of X-ray diffraction, nitrogen adsorption with calculated specific surface area and pore size distribution, as well as adsorption of Chromium (VI) and Uranium (VI) ions from aqueous solutions at various pH values.
