过渡族元素同位素研究是近几年才发展起来的研究领域,随着研究的范围日趋广泛,问题日渐深入,需要对更多的地质样品进行同位素组成测定和研究。尽管文献报道的有关用于多接收器等离子体质谱过渡族元素同位素分析的化学分离方法能将Cu、Fe、Zn等元素很好地分离开来,但并未对地质样品中复杂地质基体元素的分离情况进行报道。因此,笔者对花岗岩中Cu、Fe、Zn分离进行了研究。
A chromatographic method for separation of Cu, Fe, and Zn from granitic materials has been presented, which can satisfy the requirement of high-precision Cu, Fe and gn isotopic measurements by means of multiple-collector plasma-source mass spectrometry. The method includes employment of anion-exchange resin AG-MP-1, and elution of Cu and Fe by using HCl and of gn by using HNO3.
