Tóm tắt

HZr2P3O12 (H-form) was prepared in air at 650° C by de-ammoniation of NH4Zr2P3O12 (NH4-form) in order to study properties of proton in the NaZr2P3O12-type structure. Hydration of H-form took place at 70° C, 0.15 GPa, and the final product is (H3O)Zr2P3O12·O·17H2O (H3O-form). H- and H3O-forms reacted with alkali chloride solutions at 25° C. Rates of the exchange reactions were studied as a function of water content of H- and H3O-bearing compounds. The H-form showed an excellent selectivity for univalent cations in the order: ammonium < potassium < rubidium ≪ sodium, lithium.
