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. Injection of polyoxocomplexes of aluminium and iron in mineral structure increases the interlayer space, and a specific surface area of the material. It is shown that the intercalated montmorillonite by POM of aluminium and iron has a much higher adsorption properties than the mineral source, and the adsorption of Chromium (VI) and Uranium (VI) occurs due to the mechanism of complexation with surface hydroxyl groups, which substantially depends on pH value. For adsorption isotherms the coefficients of empirical equations of Langmuir and Freundlich were calculated. High efficiency of pillared clay minerals on the disposal of polluted waters such dangerous toxicants as uranium and chromium in the cationic and anionic forms was shown based on this study.
