| 摘 要： | 为解决盐湖卤水中的铷与大量的性质极为相近的碱金属元素钾、钠、锂、铯共存给分离带来的困难,以t-BAMBP为萃取剂,萃取分离了高钾卤水中铷钾,考察了稀释剂种类、萃取剂浓度、碱度、相比、时间等相关因素对分离的影响。结果表明,选定二甲苯体系,1 mol/Lt-BAMBP,碱度1 mol/L NaOH,相比3/1,萃取时间2 min等条件下获得纯度达99.8%RbCl。铷萃取率97.0%,反萃取率98.4%,总回收率为95.5%。

| Abstract: | Salt lake brine contains a large number of rubidium resources,but due to the extreme similarity nature of rubidium with the other coexisting alkali metals(potassium,sodium,lithium,and cesium),separation is somewhat difficult in this study.t-BAMBP,extracting agent,separates rubidium from high concentration potassium Brine.Types of thinner,concentration of extractant,alkalinity,phase ratio,time and other related factors on the separation were investigated.Xylene system,1 mol/L t-BAMBP,NaOH of 1 mol/L alkalini... |
