摘　　要：本文研究了用大孔阴离子交换树脂D301R从乏萃取剂30%TRPO-煤油溶液中净化去除脂肪酸的方法,探讨了该法用于乏萃取剂净化的可行性。The ion exchange method is used separate the fatty acids from trialkyphosphine oxides (TRPO). The TRPO has been applied to extractant for reprocessing high level liquid waste (HLLW). The fatty acids were radioysis products of TRPO by gamma ray. In the paper, four kinds of basic resin were tested. According to the experiment results weakly basic resin D301R is better adsorption resin for separation of fatty acids.
