Abstract: UO22+ -U(Ⅳ ) redox displacement chromatography on anionic bed with Fe(Ⅲ)-TiCl3-FeCl2-HCl system is studied in detail.The migration rule of steady band and the rule of distribution of UO22+ and U(Ⅳ) between two phases were clarified. Based on the fact that considerable amount of Fe(Ⅲ) is observed on the uranium plateau, the chemical reaction mechanisms occuring in the vicinity of the boundaries were proposed accordingly.
