摘要： 前报曾报导了Mn(Ⅱ)的加速效应。此后又肯定了这一效应的普遍性及应用于流洗色谱的可能性。本文发现了4NHCl中的CuCl xx-2-是一种有效的加速离子,可以改善U(Ⅵ)的色谱床效,以此实现了U(Ⅵ)、Ti(Ⅳ)和Fe(Ⅲ)的色谱分离。

Abstract: It was discovered that Cu(Ⅱ)-chloro complex ion appears accelera-tive effect to improve the chromatographic column effenciency of U(Ⅳ) species. For evaluating chromatographic characteristic was suggested a √lnC0/C' ~t graphic method by which the accelerative effect of Cu(Ⅱ)-chloro ion under different conditions was discussed. Finally, the chromatographic separation of U(Ⅳ), Ti(Ⅳ) and Fe(Ⅲ) was realized by the help of the accelerative effect of Cu(Ⅱ)-chloro ion.
