Title: Preparation and study of cesium ion-sieve for the ~(137)Cs removal from HLLW
Abstract: A new ecomaterials cesium ion-sieve(Cs-IS) has been developed by Cs +extraction/introduction reaction,and the optimum preparation conditions are determined through orthogonal experiment. The investigation on its ion exchange performance shows that Cs-IS processes the large exchange capacity (1.83 mmol/g) and high distribution coefficient (above 45 000 mL/g) for cesium. In the static exchange with the strong acid simulated HLLW,Cs-IS exhibits high exchange rate for cesium (above 96%) and large separation factor β Cs/M (large than 10 4). These indicate that Cs-IS can be used in the strong acid HLLW system for the removal and recovery of 137 Cs directly.
