合成了一种球形亚铁氰化钾钛无机离子交换剂，研究了它对模拟酸性高放废液中铯的离子交换性能。结果表明，该材料具有良好的机械稳定性和水力学性能，对艳的离子交换选择性高。在硝酸盐含量达４５０ｇ／ｌ的模拟酸性高放废液中，Ｃｓ￣＋的静态交换容量为１．０ｍｍｏｌ／ｇ（干树脂），动态（柱式流动实验）交换容量为０．８１ｍｍｏｌ／ｇ（干树脂）。
A spherical potassium ferrocyanide titanium inorganic ion exchanger was synthesized and its ion exchange performance on cesium in simulated acid high-level liquid waste was studied. The results show that the material has good mechanical stability and hydraulics, high selectivity for ion exchange. The static exchange capacity of Cs¯ + was 1.0 mmol / g (dry resin) and the dynamic (column flow experiment) exchange capacity was 0.81 mmol / g in simulated acid high level liquid waste with a nitrate content of 450 g / l (Dry resin).
