Abstract

In order to separate ceasium and rubidium,the separation methods for Cs with Cs_3Bi_2I_9 and Cs_4SiW_(12)O_(40) precipitations are studied by ~(137)Cs and ~(86)Rb radioactive indicators.The results show that the separation effect for Cs and Rb with Cs_3Bi_2I_9 precipitation is better than that with Cs_4SiW_(12)O_(40) precipitation. Under the best substoichiometric codition, the chemical recovery of Cs is 70%～80% and the separation factor for Cs and Rb is higher than 100 with the Cs_3Bi_2I_9 precipitation.
