摘要
利用一种涂结型阳离子分离交换树脂分离测定Sm-Nd年龄中的Sm、Nd二元素。本文详细介绍了这种方法的基本原理和树脂制备、装柱条件及化学分离过程。并且与测定Sm-Nd同位素年龄中的另一种Sm、Nd元素分离方法(α-羟基异丁酸HBAR分离法)进行了比较。
This paper introduces in detail the fundamental principle of using a coating type of ion ex-change resin to separate Sm and Nd for mass-spectrometic analysis used in Sm-Nd dating tech-nique, the preparation of resin, the preparation ion exchange column technique, and the chemi-cal separation process. A comparision between this method and the a-methyttatic (HBAR) me-thod for some purpose is also discussed.
