摘要
铯是稀有碱金属,在现代高科技领域具有广泛的应用前景。近年来,铯的研究与应用越来越引起人们的关注。综述了铯的用途以及提取分离技术研究的现状。分类论述了近年来国内外学者采用沉淀法、离子交换法和溶剂萃取法在铯元素分离和提取方面的研究进展,对所述技术的优缺点进行了探讨。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,为铯资源分离提取的试验研究提供了综合信息。
Cesium,a rare alkalicent metal,is of a wide range of applications in modern hi-tech area.The research on cesium attracts more and more attention now.In this paper,the applications and up-to-date extraction separation technology of Cs such as precipitation,ion-exchange,and extraction are reviewed and the advantages and disadvantages of the techniques are introduced.It was proposed that the novel extraction reagents and porous ion-exchange materials would be focused on future research for separation of cesium,and the basic research was needed to provide useful information for theoretical and experimental research.
