Abstract

Abstract

T-BAMBP with xylene extraction system was applied to separate rubidium from Cesium Raffinate. The influences of feed liquid alkalinity, the extractant concentration, organic-aqueous phase ratio, extraction time on extraction and separation efficiency were investigated. The results show that extraction rate of rubidium after four staged countercurrent extraction and four staged rinse was 94.6%. The optimum conditions were 30% volume fraction t-BAMBP of organic extractant, 0.4 mol/L feed liquid alkalinity, extraction phase ratio of 3 : 1, rinse phase ratio of 4 : 1, extraction time of 3 min. The purity of rubidium in strip liquor can be further improved through multistage extraction. This study was technical basis for obtaining high purity rubidium salt.
