本篇报道用于铷锶同位素年代测量的小柱分析流程。方法是在我们1972年草酸淋洗流程的基础上建立的。同时参考W.康普斯敦教授1977年介绍的小交换柱铷锶化学流程。样品提取方式、交换柱分离条件和操作步骤,是根据自己的实验确定的。流程有自身的特点。流程以天然硅酸盐岩石为对象,力求在一次交换过程中获得纯净的铷和锶, This article reports the small column analysis process for rubidium-strontium isotope dating. The method was established on the basis of our oxalic acid leaching procedure in 1972. At the same time, reference is made to the chemical process of rubidium strontium with small exchange column introduced by Professor W. Compton in 1977. Sample extraction methods, column separation conditions and operating procedures, is based on their own experiment to determine. Process has its own characteristics. The process of natural silicate rock as the object, and strive to obtain a pure exchange of rubidium and strontium,
