- 中文摘要: Concentration dependence of isomer shift of K/sub 2/SnCl/sub 6/ and tin(IV) chloride was studied. Tin was hydrolyzed in both cation and anion exchange resins after water washing. Two pairs of these two solutions showing the same isomer shift values, and therefore the same .nbar., were selected for further studies in HCl solutions and in anion exchange resins. The first pair was 0.04M K/sub 2/SnCl/sub 6/ and tin(IV) chloride solutions (.delta.=0.00mm/s; .nbar.=0): Their .delta.-[HCl] curves coincided each other. Tin was sorbed on anion exchange resins as pentachlorstannate(IV) at [HCl].ltoreq.6N, and chiefly as hexachlorostannate(IV) at [HCl].gtoreq.7N. The both complexes were sorbed when 6N<[HCl]<9N. The .delta.-[HCl] curves of the second pair, 0.4M K/sub 2/SnCl/sub 6/ and 3M tin(IV) chloride(.delta.=0.23mm/s; .nbar.=3), also coincided each other, and tin was sorbed as pentachlorostannate(IV) from K/sub 2/SnCl/sub 6/ solutions in the HCl concentration range studied (.ltoreq.5N).
