Abstract:
:A systematic comparative study has been performed on the various double salts based on silica. They are found to be more stable chemically and thermally than single salts of this type. Furthermore, these materials have a better selectivity for some pollutants chiefly found in the effluents of dyestuff and plating industries. The purpose of preparing a series of such materials in this study has been to evaluate their comparative usefulness under the varying conditions of pollution. The materials have been characterized on the basis of analytical studies such as chemical composition, pH titration, IR, X-ray, and TGA.
