The distribution of plutonium (Ⅲ, Ⅳ) nitrate between dilute TBP/OK and aqueous phase is systematically investigated. On the basis of the preparation and stabilization of Pu(Ⅲ, Ⅳ), the influences of the concentration of HNO3, Al(NO3)3, TBP and UO2(NO3)2 on the distribution ratio of them are studied at 25℃. The results indicate that the distribution ratio of Pu(Ⅳ) has a maximum while that of Pu(Ⅲ) increases with the concentration of HNO3. The distribution ratio of Pu(Ⅲ, Ⅳ) increases along with the concentration of Al(NO3)3 and TBP. The extraction reaction
