摘　　要：以4-叔丁基-2-(α-甲苄基)酚(t-BAMBP)为萃取剂,从除钙净化母液中萃取分离铷、钾,考察了稀释剂种类、萃取时间、t-BAMBP浓度、原料碱度、萃取相比等因素对铷、钾分离的影响。对比研究确定的较优工艺条件为:以tBAMBP为萃取剂,磺化煤油为稀释剂,萃取剂浓度为1 mol/L,料液碱度为0.4 mol/L,相比(O/A)为2,萃取时间5 min,铷的萃取率可达90%,实现了铷钾分离。The process of separating Rb and K from mother liquor after removing calcium was investigated by using 4-tbutyl-2（α-methylbenzy） phenol （t-BAMBP） as extractant. The effects of thinner, extraction time, alkalinity of material, concentration of t-BAMBP, extraction phase ratio and other related factors on the separation of Rb and K were investigated. The optimal conditions were as follows： t- BAMBP as extractant, sulfonated kerosene as thinner, concentration of 1.0 mol· L-1 , c （ OH- ） = 0. 4mol · L-1 , extraction phase ratio of 2, extracting time of 5 min. The extraction rate of Rb was 90%, the separation of Rb and K was obtained.
