We have studied about separation of An and Ln using diglycolamide (DGA) compounds, which is developed in our laboratory. Thus we have the results of separation of over 97% Nd and under 2 % Am in organic phase and 98% Am and 3% Nd in aqueous phase using multi-stage extractions. DGA can extract many metal ions, the behavior of Sr, Tc and Pd at the separation condition of An/Ln will be presented.
