溶液体系中铯分离提取技术的研究进展

Progress on Cesium Separation and Recovery from the Salt Lake Brines

金属铯及化合物在能源和航天等新兴领域具有广阔的应用前景,中国盐湖卤水中富含铯资源,但目前对铯资源的开发利用仍为空白。开展铯资源提取及合理利用对国民经济快速发展十分重要。总结了沉淀法、离子交换法、萃取法等方法在溶液体系中分离提取铯方面的进展,并加以简要评述。同时也为盐湖卤水铯资源的有效开发提供了参考。

Cesium metal and its compounds have a wide application prospect in the new field such as energy and space technology.Although there are large amount of cesium resources in Chinese salt lake,the effective techniques for separation and recovery of cesium from brines are still scare.With the rapid development of China＇ s national economy,supplementary imports of cesium will form an increasingly important component of China＇ s energy structure.Progress of extractive methods,such as precipitation method,absorption method,extraction method etc.In terms of cesium separation and recovery in solution system were summarized,advantages and disadvantages of each method were also briefly reviewed.compared.Reference for the exploiting of cesium resource from salt lake was provided too.
