TL;DR: Ion exchange of the ammonium, potassium, and cesium salts of 12-tungstophosphoric and 12-molybdophoric acids has been studied at 298 K.
Abstract: Ion exchange of the ammonium, potassium, and cesium salts of 12-tungstophosphoric and 12-molybdophosphoric acids has been studied at 298 K. Residual protons contained in the nonstoichiometric salts are exchanged as well as the original cations. The completeness of the ion-exchange process varied from approximately 5 to 70%, depending on both the solid phase and liquid phase cations. The maximum exchange capacities are shown to decrease significantly as the size of the cation leaving the solid becomes larger than that of the cation entering the solid.
