Silica Based Double Salts as Cation-Exchangers II. Synthesis and Analytical Applications of Sn(IV) Phosphosilicate

Abstract

This paper deals with the synthesis of Sn(IV) phosphosilicate as a new, reproducible and stable inorganic ion-exchanger. The composition, ion-exchange capacity for different metals, pH titrations, chemical stability, distribution and IR studies have also been performed on a sample of this material. On the basis of distribution studies, a number of binary separations of analytical importance have been achieved. The limits of separations have also been determined by taking various ratios of the two components.
