摘要: 本文使用国产SY-202高速离子交换色谱仪(库仑检测器)以及国产YSGSO3Na型阳离子交换树脂,用自行装配的梯度装置,以α-羟基异丁酸(α-HIBA)为洗脱液,提出浓度和pH并行变化的梯度形式,快速分离了十三个稀土元素;并讨论了该种梯度形式的特点及各种定量关系;研究了稀土元素的色谱行为与其结构之间的关系及效应;考察了库仑检测器电解效率的变化原因及规律,并定量测定了镥、镱及铥。

Abstract: The 13 rare earth elements were rapidly separated within an hour by using the cation exchange resin of China-made type of YSG-Na, the high speed ion exchange chromatograph of China-made type of SY-202 with a coulometric detector, and a simple out-gradient apparatus installed by us. a-HIBAwas used as eluant. The concentration and pHvaried simultaneously in the given gradient condition.
