除Sr、Cs无机交换剂的制备及性能

Preparation and Ion-Exchange Property of Inorganic Ion-Exchanger for Strontium and Cesium Removal

为去除废液中的Sr、Cs等裂变产物,用制备的亚铁氰化铜钾和亚铁氰化钴钾无机交换剂进行了初步研究。结果显示,亚铁氰化铜钾交换剂对Sr、Cs离子的静态饱和交换容量最大值分别为80、160 mg g,对Sr、Cs离子的动态交换容量最大值分别为17、130 mg g;亚铁氰化钴钾交换剂对Sr、Cs离子的静态饱和交换容量最大值分别为80、70mg g,对Sr、Cs离子的动态交换容量最大值分别为0.4、70 mg g。

In order to remove the fission product, such as strontium and cesium. The inorganic ion-exchangers, such as copper ferrocyanide （CuFe） and cobalt ferrocyanide （CoFe）, were prepared and used for research. We have done some research on the preparation techniques and adsorption of cesium or strontium in the solutions. The result shows that the maximum static ion-exchange capability of CuFe for Sr and Cs are respectively 80 mg/g and 160 mg/g, the maximum dynamic ion-exchange capability for Sr and Cs are respectively 17 mg/g and 130 mg/g. The maximum static ion-exchange capability of CoFe for Sr and Cs are respectively 80 mg/g and 70 mg/g, the maximum dynamic ion-exchange capability for Sr and Cs are respectively 0.4 mg/g and 70 mg/g.
