The objective of this work was to investigate the acid-base properties of materials based on zirconium(IV) phosphate and diphosphate and to calculate the equilibrium constants for corresponding heterogeneous reactions of binary ion exchange, that is, to calculate the characteristics of the ion-exchange properties for use in calculating more complicated ion-exchange equilibria. The objects of investigation were zirconium(IV) hydroxyphosphate (ZHP) and zirconium(IV) diphosphate (ZDP), as well as composite materials based on said compounds and a porous support material.
