氧化还原离子交换法分离铀同位素取得了可喜的进展。该法能够成功取决于两个基本因素:足够大的同位素富集系数和足够快的U(Ⅳ)-U(Ⅵ)的同位素交换速率。因此,两者成为离子交换法分离铀同位素的基本研究内容。近年来,不少作者较深入地研究了在各种环境内,特别是盐酸介质中的U(Ⅳ)-U(Ⅵ)的电子交换反应的动力学,得到了半交换期小于0.1s的结果。从而在日本建立了盐酸为介质的阴离子交换法富集铀同位素的中间试验工厂。
Redox ion exchange method of uranium isotopes made encouraging progress. The method can successfully depend on two basic factors: a sufficiently large isotopic enrichment factor and a sufficiently fast isotopic exchange rate of U (IV) -U (VI). Therefore, the two have become the basic research content of ion exchange separation of uranium isotopes. In recent years, many authors have studied the kinetics of the electron exchange reaction of U (IV) -U (VI) in various environments, especially in hydrochloric acid medium, and obtained the results that the half exchange period is less than 0.1s . Thus in Japan established a hydrochloric acid as the medium anion exchange enrichment uranium isotopes of the pilot plant.
