摘　　要：本文合成了 N、N'——二 (邻氧乙酸 )苄叉乙二胺 ,并讨论了其对 Fe3 +、Al3 +、Th4+、L a3 +、Eu3 +、U O2 +2等离子的分离沉淀条件。结果表明 :它是 Fe3 +、Al3 +、Th4+、L a3 +、Eu3 +、U O2 +2 良好的沉淀剂 ,且控制 p H值在 4.0～5 .0之间时 ,可以一次性定量将 Th4+— Eu3 +、Th4+— L a3N,N'-bis(O-oxy-acetate)benzyl-diamine has been synthesized,and the precipitating conditions of Fe 3+ ,Al 3+ ,Th 4+ ,La 3+ ,Eu 3+ and UO 2+ 2 with it has been studied in this article The results show that it is very superior precipitant of Fe 3+ ,Al 3+ ,Th 4+ ,La 3+ ,Eu 3+ ,UO 2+ 2,and only once can it separate Th 4+ -Eu 3+ ,Th 4+ -La 3+ successfully in 4 0~5 0 pH value
