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。
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.
