SYNTHETIC INORGANIC ION EXCHANGERS AND THEIR APPLICATIONS IN ATOMIC ENERGY
Highly stable, granular, selective ion exchangers are being studied with a view to their application to the treatment of high-temperature pressurizcd water, chemical separations in intense radiation fields, and for normal separations where increased specificity is desirable. These materials include zirconium phosphate, arsenate, tungstate, molybdate, and oxide; oxides and phosphates of thorium and titanium, and tungsten oxide. The salts possess cation- exchange properties; tungsten oxide is a cation-exchanger, while the other oxides are amphoteric amd may be used for either cation or anion exchange deponding on the conditions. In the case of zirconium phosphate, the effect of variation in manufacturing method on the properties of the product has been studied on the 1 kg scale using standard pilot-scale equipment, and several large batches have been prepared for comparative testing, over a range of mesh sizes suitable for large-scale column operation.
