| 摘 要： | 介绍了地质年龄测定中对高Ｒｂ／Ｓｒ样品，用吸附了六硝基二苯胺的阴离子交换树脂除去部分铷元素的新方法，从而实现样品在阳离子交换柱上的铷锶完全分离。该方法可解决Ｒｂ／Ｓｒ＞２０样品在质谱分析测定中￣（８７）Ｒｂ干扰￣（８７）Ｓｒ的问题。文章中对Ｒｂ／Ｓｒ＞２０的地质样品部分除铷法与其它方法进行了对照测试，结果一致。部分除铷法比其它方法具有节省时间、操作简便的优点

| Abstract: | This paper reports a new sample processing method in geological agedetermination. When the Rb/Srvalue of the sampleishigher than 20,the extra rubidiumcan be patially removed by anion-exchange resin through absorbing six nitro biphenylamine. This method is called rubidium partial removing method.It can easily separaterubidium from strontium on the cation-exchange column. Compared with othermethods,this method is easy to operate and save time. |
