Many inorganic ion exchangers have been studied for the removal of strontium and cesium ions, due to their high selectivity for specific cations, thermal and radiation stabilities [1 S], In spite of those advantages, they have been limted in their extensive applications because of the pressure drop problem in column operation when they are used in microcrystalline or powdered form. To solve this problem, in the case of synthetic zeolites, clay minerals are often used for pelletization, but it still causes dissolution of clay minerals in aqueous solution.

Removal of Strontium-90 from Basin Water in a Plant-Scale Column. Amberlite-200 was selected for use in the plant-scale ion-exchange column because (a) a large volume was processed (1200 column volumes) before 1% breakthrough occurred, (b) a reasonably large volume was obtained before 50% breakthrough (a measure of capacity) occurred, (c) it is a macroreticular resin that is resistant to physical degradation, and thus provides high flow rates, and (d) it is readily available at a reasonable cost.
