• Tin(IV)-edta compound has been synthesized by mixing aqueous solutions of tin(IV) chloride and disodium salt of ethylenediaminetetraacetic acid (EDTA=H<SUB>4</SUB> edta) in different conditions. The most stable sample is prepared by mixing 0.1 mol dm<SUP>−3</SUP> solution of tin(IV) chloride with 0.1 mol dm<SUP>−3</SUP> solution of disodium salt of edta in the volume ratio of 3:2 at pH 2.5 and refluxing the mixture for 16 h. Ion exchange capacities of the material for alkali metals are significantly smaller (0.26–0.20 mequiv./g) than for alkaline earths (0.74–0.40 mequiv./g). The thermal and chemical stability of this material has been compared with amine-tin hexacyanoferrate(II). Analytical importance of this material has been established by achieving a number of quantitative separations on its columns.
