摘要
60年代以来人们十分关注用离子交换法从酸性高放废液中去除和回收137Cs。本文对比和评价了沸石、多价金属磷酸盐、磷钼酸铵及其复合离子交换材料、不溶性亚铁氰化物、钛硅化合物等无机离子交换剂。结合笔者的最新研究成果 ,并考虑了含铯废液交换剂的进一步处置问题 ,提出了为我国生产堆高放废液中去除 137Cs的无机离子交换材料 。
The separation of Cs from the high level liquid waste by inorganic exchangers has received much attention during the last three decades. The paper summarizes and compares five series of inorganic ion exchangers such as zeolites, multivalent phosphates, ammonium molybdophosphate and complex inorganic exchangers, insoluble hexacyanoferrates, crystalline silicotitanates. Based on the recent work ourselves and the treatment of cesium bearing inorganic ion exchangers, promising materials for removal of cesium from the Chinese HLW was presented.
