The isotopic enrichment of 232U and 234U against 238U in the U(IV)-U(VI) exchange process has been studied by anion exchange chromatography. The enrichment of 232U in the uranium adsorption band was monitored by the activity ratios measured by α spectrometry and the isotopic abundances of 234U were determined by mass spectrometry. The results have shown that the isotopic enrichment is proportional to the mass difference among isotopes of 232U, 234U and 238U. The anomalous isotope effect previously observed for 235U was not observed for 232U. The ideal separation coefficient, εo (=S-1), between two isotopes of 232U and 238U at the ideal distribution state in the U(IV)-U(VI) exchange system has been inferred as 2.2×10-3 at 308K.
