Study of Separation of Cs and Rb With Precipitation Process

  • 摘要: 以137Cs和86Rb为示踪剂对硅钨酸铯和碘铋酸铯两种沉淀法分离Cs和Rb进行了研究。结果表明,碘铋酸铯沉淀法比硅钨酸铯沉淀法分离效果好;采用亚化学计量的碘铋酸钾分离时,Cs沉淀率可达70%~80%,Cs、Rb的分离因数大于100。
    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.
