目前,离子交换分离技术在分拆化学和同位素地质实验技术、水的净化等方面得到了日益广泛的应用.特别是在铷一锶年代学和锶同位素地质学的实验技术中,应用离子交换技术从岩石矿物中分离、纯化微量测和锶以制备符合质谱分析要求的样品是一种必不可少、行之有效的方法.为适应Rb—Sr年代学、锶同位素地质学和质谱测试技术迅速发展的要求,作者在原来工作的基础上,对分离纯化Rb、Sr的实验技术作了较大的改进,取得了一些新的进展.现将有关资料综述如下.
At present, ion exchange separation technology has been widely used in spin-off chemistry and isotope geological experiment technology, water purification, etc. Especially in the experimental technology of rubidium-strontium chronology and strontium isotope geology, ion exchange technology The separation and purification of trace and strontium from rock minerals is an indispensable and effective method to prepare samples that meet the requirements of mass spectrometry analysis.For the Rb-Sr chronology, the technology of strontium isotope geology and mass spectrometry has developed rapidly On the basis of the original work, the author made great improvements on the experimental techniques for the separation and purification of Rb and Sr, and made some new progresses. The relevant information is summarized as follows.
