Crystalline cerium(IV) phosphates—II The ion exchange characteristics with alkali metal ions Academic Article uri icon

abstract

  • The ion exchange behavior of seven crystalline cerium(IV) phosphates towards some of the alkali metal cations is described. Only two of the compounds (A and C) possess ion exchange properties in acidic solutions. Four others show some ion exchange characteristics in basic media with some of the alkali cations. Compound G does not behave as an ion exchanger in solutions of pH < 12. Compounds B, D and F exchange Li+, but show very little Na+ uptake. Compound E undergoes ion exchange with Na+ and Cs+, but not with Li+. Both Li+ and Na+ are sorbed by compounds A and C. The results are indicative of structures which show steric exclusion phenomena. © 1976.
