Uranium Isotope Fractionation Occurred in Anion Exchange Chromatography Using Uranyl Acetate and Uranyl Citrate Complexes

Abstract

An ideal displacement chromatographic migration of uranium has been accomplished on an anion exchange resin column using uranyl acetate and uranyl citrate complex formations, respectively. Uranium isotope fractionation occurred in the anion exchange chromatography was measured by isotopic analysis and the direction of isotope enrichment was confirmed to be same as the direction observed in cation exchange chromatographies. The magnitudes of the isotope effect obtained were discussed by comparison with those obtained by cation exchange chromatographic processes.
