Research Progress in the Methods for the Removal of Cesium from Radioactive Liquid Waste

随着核工业的发展,放射性废液的去除越来越受到重视。本文介绍了离子交换法、溶剂萃取法、吸附法、膜分离法和化学沉淀法以及组合工艺等放射性废水中铯的去除方法,对每种方法的原理、特点及应用情况进行了评述,对放射性铯去除方法的研究方向和发展趋势进行了展望。本文对于针对不同情况的放射性污染科学选用放射性铯的去除方法具有较大参考价值。

With the development of nucleus industry,the removal of radioactive liquid waste has been paid more and more attention. The research progress in the methods including ion exchange,solvent extraction,adsorption method,membrane separation,chemical precipitation and combination processes,which have been frequently used for removing radioactive liquid waste containing cesium were summarized in this paper. The advantages and disadvantages of various methods were compared,and the future direction of methods for the removal of radioactive cesium was also discussed. The paper has great reference value for the removal of radioactive cesium for radioactive pollution in different situations.
