Title: THE AMP PROCESS FOR CAESIUM SEPARATION. I. ADSORPTION OF CAESIUM ON AMMONIUM 12-MOLYBDOPHOSPHATE

Abstract

The maximum saturation" capacity of ammonium 12molybdophosphate (AMP) for cesium, determined on colurans of AMP-asbestos as well as on coarse AMP alone, is about 0.70 meq/g, i.e., about 1.4 of the three ammonium ions are exchangeable for cesium. Addition of nitric acid to the feed solution to a concentration of 3N has only a slight effect on the capacity. Approximately half of the cesium adsorbed at saturation'' is reraoved by prolonged washing with strong acid (e.g. 3N HNO/sub 3/), the rate of elution progressively diminishing as raore of the cesium is displaced. The other half, however, cannot be eluted except with concentrated solutions of those cations that also form insoluble 12- molybdophosphates. Cesium may be selectively adsorbed on AMP from acid fission product waste concentrates, and all other fission product nuclides, except Rb and Zr/sup 95/- Nb/sup 95/, quantitatively removed by an acid wash.
