SYNTHETIC INORGANIC ION-EXCHANGE MATERIALS. I. ZIRCONIUM PHOSPHATE
Some of the properties of zircorium phosphate are given as an example of a class of very stable synthetic inorganic ion-exchange materials, which may be prepared in granular form suitable for column operation. It exhibits properties typical of a polyfunctional, weakly acid cation exchanger, with capacities up to ~ 5 mequiv/ g in alkaline solution. Materials with a low phosphate: zirconium ratio possess in addition anion--exchange properties due to anions retained in the structure from the original zircorium salt. Cations may be exchanged rapidly and reversibly upon acid phosphate groups in the gel structure. Distribution coefficent measurements for alkali metal and alkaline earth ions have been made, and the material shows promise for separation purposes; uptake is reduced at elevated temperatures owing to hydrolysis. The stability of the material towards water at temperatures up to 300 deg C suggests its possible use for water treatment in high-temperature systems, as well as other possibilities. (auth)
