亚铁氰化钾锌类交换剂去除Cs~+的初步研究

摘要: 合成了亚铁氰化钾锌类无机离子交换剂并测量了其在模拟高放废液中对Ｃｓ~＋的静态吸附容量。结果表明，每克干离子交换剂对Ｃｓ~＋的静态吸附容量为０．９─１．０ｍｍｏｌ／ｇ；用溶胶－凝胶法制成的亚铁氰化锌钛小球静态吸附容量为０．７２ｍｍｏｌ／ｇ。亚铁氰化锌类交换剂可作为从酸性高放废液中去除~（１３７）Ｃｓ的材料。

Abstract: STUDY OF REMOVING Cs~＋ BY ZINC FERROCYANIDEWang Shizhu;Jiang Changying(Institute of Nuclear Energy Technology, Tsinghua University, P.O.Box,1021，Beijing102201)Abstract: The Zinc ferrocyanide inorganic ion exchanger is synthesized and the static exchange capacity for Cs＋ from a simutated acidic high level radioactive liguid waste（HLLW）is measured．The experimental results show that the static exchange capacity for lg dry exchanger is 0．9─1．0 mmol／g and 0．72 mmol／g for potassium titanium hexacyanoferrate by sol-gel method. The zinc ferrocyanide inoganic can be used for removing Cs~＋ from HLLW.Keywords:Zinc ferrocyanide Cs＋ HLLW Inorganic ion exchanger
