摘要： 本文研究了UO22+-U(Ⅳ)在阴床-Fe(Ⅲ)-TiCl3-FeCl2-HCl体系中的氧化-还原排代色谱.阐明了稳定区段的移速规律和铀坪中UO22+和U(Ⅳ)在两相中的分配律,发现铀坪中存在可观量的FeⅢ.据此,提出了铀区段前后沿进行的反应机制.

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.
