Effect of the Drying Temperature on the Ion-Exchange Properties of Zirconium Phosphate

摘要

The ion-exchange properties of zirconium phosphate, dried at temperatures ranging from 1500 to 8500, are compared with those of zirconium phosphate dried at 500. In addition to partially irreversible dehydration, permanent changes in certain properties of zirconium phosphate dried at temperatures above 150 ° could be observed. Variations in selectivity for certain ions of ZP dried at high temperature can be employed to improve the separation of these ions from each other. All phenomena observed can be explained by the assumption that an increase in drying temperature causes a greater condensation in the structure of the exchanger.
