萃取法（t—BAMBP）提取卤水中铷、铯及其影响因素分析

研究以t-BAMBP为萃取剂，萃取分离Rb、Cs，同时考察料液中碱金属元素Na、K对铷、铯萃取效果的影响。研究得出：碱金属元素Na对实验体系中铷、铯的萃取没有影响：碱金属元素K对体系中铷的萃取影响较大，随着溶液中K浓度的增大，铷的萃取率逐渐减小；碱金属元素K对铯的萃取率影响较小，可忽略。该研究主要针对江陵凹陷富钾卤水中铷、铯的提取技术进行探索。

Study on the Extraction of Rb and Cs with Extraction Method and the Influencing Factors Analysis

Study on using t-BAMBP as extraction agent to extract and separate Rb,Cs and meanwhile investigate the influence of alkali metal elements Na,K in the feed liquid on the extraction effect of rubidium, cesium extraction effect. We conclude that alkali metal element Na has no influence on the extraction of rubidium, cesium while alkali metal element K has great influence on the extraction of rubidium in the system. With the increasing of K concentration in the solution, the extraction rate of rubidium reduces gradually. However, alkali metal element K has little influence on the extraction rate of cesium which can be ignored. This study focus on the extraction technology exploration of rubidium and cesium in depression of potassium rich brine of Jianglin.
