摘　　要：介绍了Rb、Cs资源的分布和应用,将其提取方法分类为沉淀法、萃取法、溶液离子交换法以及盐-醇-水三元体系相平衡基础理论研究,并进行了分析比较.认为离子交换法和萃取法应用于工业化生产最具发展前景,通过对这2种方法提取Rb、Cs的关键问题的分析,提出了冠醚、杯冠醚萃取试剂和新颖的多孔离子交换材料的开发将成为未来提取分离Rb、Cs的研究热点,为Rb、Cs资源分离提取的实验研究提供综合信息.The distribution and applications of Rubidium and Cesium resources were introduced. From the analysis and comparison of typical separation methods, that is, precipitation method, extraction method, and ion-exchange method, the result showed that the ion-exchange and the extraction methods were the most prospect separation methods for the industrial production. With the analysis of the key issues of two separation methods, it was proposed that the novel calixcrown extraction reagents and porous ion-exchange materials would be hot spot of the future research for separation of Rubidium and Cesium, and the basic research on salt/alcohol/water Ternary system equilibrium was needed to provide useful information for theoretical and experimental research for the separation of Rubidium and Cesium.
