摘要： 研究了柠檬酸、酒石酸、乳酸、丁二酸、亚氨基二乙酸及乙酰丙酮为配合剂时的U(Ⅳ)-U(Ⅵ)Redox排代色谱学。着重讨论了羧酸为配位剂时提高铀同位素富集因子的可能性及途径。

Abstract: Cationic ion exchange U(Ⅳ)-U(Ⅵ) redox displacement chromatography with citric, tartaric lactic, succinic,iminodiacetic acid and acetylacetone as complex agent was studied. The possibility and way to obtain high enrichment factor of uranium isotope separation as carboxylic acid is used as complex agent was mainly dealted. From the results it may be expected to increase the enrichment factor to (8.5-9.0)×10-4, approaching the level offered by ion exchange process, if carboxylic acid is correct selected and its concentration as well as displacement ion concentration are properly controlled.
