Abstract

The back extraction of UO 2 2+ ,Pu(Ⅳ),Am 3+ and TcO 4 - with 2 hydroxyethyl 1,1 diphosphonic acid (HEDPA) solution from 30 % TRPO(mixed trialkyl phosphine oxide)/ kerosene and 20 %TRPO 20 %TBP(tributyl phosphate)/kerosene systems is studied. Two kinds of HEDPA with different purity are compared. The effects of nitric acid concentration and HEDPA concentration on the back extraction are demonstrated. Based on the experimental results , a TRPO process using HEDPA as the back extractant is proposed.
