Abstract:
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 of chemical precipitation and ion exchange,which have been frequently used for removing radioactive liquid waste containing cesium are summarized. Besides,several new approaches developed in China and abroad are introduced. It is pointed out that the ion exchange process using transition metal ferrocyanides and silicotitanates as ion exchangers for treating cesium containing wastewater has promising future.
Key words:
