U(Ⅳ),U(Ⅵ)在萃取分离过程中的同位素交换

THE ISOTOPE EXCHANGE BETWEEN U(Ⅳ) AND U(Ⅵ) IN SEPARATEION PROCESS BY EXTRACTION

摘要: <正> 一、引言近年来不同价态之间铀同位素交换速度的研究,越来越引起人们的重视。其原因是铀同位素交换速度的快慢,直接关系到铀同位素分离的成败,因而研究铀同位素交换速度,是一个很重要的问题。通过实验发现U(Ⅳ),U(Ⅵ)在萃取分离的瞬间,有同位素交换现象,尤其在Fe~(2+)的

Abstract: In the paper, the exchange of isotope between U (Ⅳ) and U (Ⅵ) and Fe~(2+)catalytic action in its separation process by solvent extration is studied.
