摘要
90Sr的去除是放射性废水处理的研究重点之一。从卤水矿资源中分离提取锶,是具有重要实际意义的资源开发研究课题。吸附法凭借其特有的优势,已经成为去除和分离提取锶较为经济和适宜的手段之一。本文综述了采用无机离子交换剂、有机离子交换树脂、生物类吸附剂等分离提取锶的最新研究进展,并对吸附机理进行了讨论,探讨了吸附法分离提取锶的发展方向。
The removal of 90Sr is a key aspect during the treatment of radioactive waste water.Extraction of strontium from brine is also an important and valuable issue.Adsorption has become an economical and appropriate method for separating strontium by virtue of its unique advantages.In this paper,the research progress in strontium adsorption using inorganic ion exchangers,organic ion exchange resins,crown ether-containing adsorbents,and molecularly imprinted adsorbents,etc.has been reviewed.The adsorption mechanisms and the prospects in strontium adsorption separation have been discussed.
