Synthesis and sorption properties of Ti- and Tі/Al-pillared montmorillonite
Abstract
The influence of aluminium and titanium polyhydroxocomplexes on the structural and adsorption properties of pillared montmorillonites has been investigated. Structural characteristics of pillared montmorillonites, such as interlayer space, specific surface area, and pore size distribution are found to depend on the composition and synthesis conditions of polyhydroxocomplexes. Carried out researches on the sorption of uranium(VI) and chromium(VI) showed a significant effect of pH on the adsorption properties of the obtained materials. It has been shown that montmorillonite pillared with mixed aluminum and titanium polyhydroxocomplexes shows increased adsorption properties relative to retrieve ions of chromium(VI) and uranium(VI) from aqueous solutions.References
