The ion exchange properties of ceric phosphate were investigated including rates of reaction, distribution coefficients of alkali metals, capacity and column behavior of some elements. Ceric oxide was shown to possess anion exchange properties in acid solution and cation exchange properties in basic solution. The two compounds have properties analogous to, but not identical with, zirconium oxide and phosphate. Cesium and barium were successfully separated on a short column of ceric phosphate at room temperature. These inorganic ion-exchangers show promise of providing additional means for effecting and widening the scope of radiochemical separations, an important and necessary consideration in the radioactivation analysis, of trace elements in ultrapure materials.
