The extraction behavior of trace Am(Ⅲ) and Eu(Ⅲ) from nitrate medium withHEHEHP in kerosene was studied. LgD/pH and lgD/[H2A2] dependence plots are given. Calculated values of lgKex for Eu, Nd and Am are -0.13±0.08, -1.36± 0.10,-1.89± 0.18, respectively. Extraction equilibrium equations were deduced under proper conditions. Calculated values of DA. and DRE are in accordance with experimental oiles.
