摘要

用醋酸铀酰和柠檬酸铀酰络合物分别在阴离子交换树脂柱上实现了铀的理想置换色谱迁移。通过同位素分析测定了铀同位素在阴离子交换色谱中发生的分馏,证实了铀同位素富集的方向与阳离子交换色谱中观察到的方向一致。通过与阳离子交换色谱法比较,讨论了同位素效应的大小。

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