Perchloric acid effect on the extraction of uranyl nitrate by TBP in CCl4
Written by sctunisie no commentsPerchloric acid solutions (from 0 to 10 M) were added into nitric aqueous solutions (0-3 M) of uranyl nitrate (roughly 0,1 M). Then Uranium was extracted by 30% TBP in CCl4. These additions yield to a very large increase of the distribution coefficient for uranium. HClO4 "synergic effect" on the extraction of uranium is discussed on the basis of the study of the uranyl ion behaviour in the nitro-perchloric aqueous medium.
