| 摘 要： | 引言 用与水不相混溶的有机萃取剂作淋洗剂的离子交换色层法提出于1975年。1979年杨伯和等人用三脂肪胺硫酸盐的煤油溶液从吸附有铀的阴离子交换树脂上洗脱出高纯度的铀。1980年何寿椿等人用四苯硼钠的甲基异丁基酮等的溶液作淋洗剂在阳离子交换树脂柱上实现了Rb和Cs的分离。与此同时,江林根等人用HDEHP的煤油溶液作淋洗剂,在阳离

| Abstract: | 170Tm, 152,154En, 147Pmand141Ce are separated on the anion exchange resin column by gradient elution using organic extractant HEHEHP-kerosene as eluant. The equilibrium distribution ratios of these rare earth elements between the ion-exchange resin and extractant phases are determined. Both the dependence of lg D to lg [H ] and that of lg D to lg [(HEHEHP)2] are linear; with a slope of about -2 and 2 respectively. |
