| 摘 要： | 以二甲苯作稀释剂, 采用有机萃取剂t-BAMBP萃取分离低浓度铯铷溶液中的铯、铷。考察了OH-浓度、萃取剂浓度、萃取相比和萃取时间对铯和铷萃取率及分离系数的影响。结果表明: 在c(OH-)＝0.1 mol/L, c(t-BAMBP)＝0.7 mol/L, 萃取相比为0.7, 萃取时间为1 min时, 铯萃取率达到84.43%, 铯铷分离系数达到7.26, 分离效果较好。

| Abstract: | The separation of rubidium and cesium from a kind of solution containing low concentrations of rubidium and cesium with organic extractant t-BAMBP was investigated. The influences on rubidium and cesium extraction rate and separation coefficient by factors, including concentration of OH-, concentration of t-BAMBP in xylene, O/A and extraction time, were examined. Results showed that with the concentration of OH- at 0.1 mol/L, the concentration of t-BAMBP at 0.7 mol/L, O/A of 0.7 and the extraction time of 1 min, the cesium extraction rate reached 84.43% with the separation coefficient at 7.26, showing a good separation result obtained. |
