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
INTRODUCTION Ion exchange chromatography with water-immiscible organic extractants as eluent was proposed in 1975. In 1979, Yang Bo and others eluted high-purity uranium from the anion exchange resin adsorbed with uranium using the tertiary fatty amine sulfate kerosene solution. In 1980, He Shouchun and others used tetraphenyl boron sodium methyl isobutyl ketone solution as the eluent on the cation exchange resin column to achieve the separation of Rb and Cs. In the meantime, Jiang Lingen and others use HDEHP kerosene solution as eluent in the cation
