In particula r, the effects of neodymium on the cesium ion exchange and the Cs+ selectivity v ariation on Cs-IS owing to introduction of rare earth elements into HLLW were s tudied. Though rare earth elements exhibit a small influence on the distributio n coefficient for Cs+, they impair Cs-exchange capacity of Cs-IS to some ext ent. This interruption on the selectivity to Cs+ can be significantly eliminat ed provided an appropriate ratio of liquid to solid V:m is used.展开更多
