Abstract

A new cesium ion-sieve (Cs-IS) was developed by cesium ion extraction/introduction reaction with ZMPP. The investigation on its properties showed that Cs-IS not only remains the similar microcrystalline structure of ZMPP, but also carries forward the large exchange capacity for cesium and good chemical stability in the medium of 3mol/dm³ HNO₃ from ZMPP. In the static exchange with the strong acidic simulated HLLW, Cs-IS exhibits high exchange rate for cesium and large separation factor β_Cs/M.
