| 摘 要： | 铷、铯在地壳中含量颇丰,近年铷铯在新兴应用领域中显示出强劲的生命力。研究以t-BAMBP为萃取剂用于模拟料液萃取分离铷、铯,同时探索碱金属元素钠、钾对铷、铯萃取结果的影响。研究得出:碱金属元素钠对实验体系中铷、铯的萃取没有影响;碱金属元素钾对体系中铷的萃取影响较大,随着溶液中钾浓度的增大,铷的萃取率逐渐减小;碱金属元素钾对铯的萃取率影响较小,可忽略。

| Abstract: | The process of extraction and influencing factor of Rb and Cs with t - BAMBP is investigated. T -BAMBP is extracting agent for extracting and separating Rb and Cs. The influen- cing factor of Na and K to the extracting of Rb and Cs is also studied. The study showed that alkali metal of Na had no effect on extraction of Rb and Cs and Alkali metal of K had a greater impact on extraction of Rb. With the increasing concentration of K in the concentration, the extraction rate of Rb decreased gradually. K has a smaller impact on extraction of Cs. It can be ignored. This re- search is aimed at deep potassium - bearing brine in Jiangling depression. |
