中文摘要: 针对铷浸出液含量低的特点,通过考察相比等因素对铷萃取的影响,得到最优的萃取条件为:1.5 mol/L t-BAMBP、相比O/A=1/1、时间2 min、温度40 ℃、3级逆流萃取,铷萃取率达到94.67%,实现了铷与钾、钠分离。控制条件对载铷有机相逆流洗涤,负载有机相中钾、钠脱除率分别为98.95%和95.70%,保证了铷化合物的纯度。
Abstract:Based on low content of rubidium in lixivium, effect of phase ratio (O/A) on rubidium extraction was investigated. The results show that rubidium extraction rate of three-stage countercurrent extraction is 94.67% and rubidium is separated from potassium and sodium under the optimum conditions including t-BAMBP concentration of 1.5 mol/L, O/A=1/1, extraction time of 2 min, and temperature of 40 ℃. 98.95% of potassium and 95.70% of sodium in rubidium-loaded organic phase is removed by countercurrent washing, which purity of rubidium compound is ensured.
