A comprehensive study of the preparation of hydrous tin(IV) oxide ion-exchangers was made by using eight systems: (1)Na<SUB>2</SUB>[Sn(OH)<SUB>6</SUB>]–H<SUB>2</SUB>SO<SUB>4</SUB>, (2)Na<SUB>2</SUB>[Sn(OH)<SUB>6</SUB>]–H<SUB>2</SUB>SO<SUB>4</SUB>(boiling), (3)Na<SUB>2</SUB>[Sn(OH)<SUB>6</SUB>]–HCl, (4)Na<SUB>2</SUB>[Sn(OH)<SUB>6</SUB>]–CH<SUB>3</SUB>COOH, (5)SnCl<SUB>4</SUB>–NaOH, (6)SnCl<SUB>4</SUB>–NH<SUB>3</SUB>aq, (7)SnCl<SUB>4</SUB>–NH<SUB>3</SUB>aq(boiling), and (8)SnCl<SUB>4</SUB>-pyrohydrolysis. From a detailed examination of the dependency of the yield, the ion-exchange behavior toward Na<SUP>+</SUP> and Cl<SUP>−</SUP> ions, the composition, and some other properties on the conditions for precipitation, it was found that the ion-exchange characteristics are similar among materials produced from the systems from (1) through (7) if we neglect some aging effect of boiling, while the difficulty of synthesis differs according to the systems. The materials obtained from the (8) system, however, showed titration curves different from those for the exchanges obtained from the other systems and had less cation-exchange capacity for Na<SUP>+</SUP> by 20 per cent. From these results, it is concluded that the simplicity of the synthetic procedures in the most important criterion for choosing the best conditions for preparing the exchanger.
