在地球化学勘查中,砷、锑、铋、汞等元素的分析是十分重要的。然而这些元素的克拉克值都很低,用常规化学分析和仪器分析很难测定。本文根据参考文献(1)(2)和有关资料1)的报导并结合本人实践,介绍一个简单、快速测定化探样品中微量砷、锑、铋、汞的氢化物——无色散原子荧光光谱法。 In geochemical exploration, arsenic, antimony, bismuth, mercury and other elements of the analysis is very important. However, the Clarke values ​​for these elements are very low and are difficult to determine by routine chemical and instrumental analyzes. Based on the reports of reference (1) (2) and related data 1) and combined with my own practice, this paper presents a simple and rapid method for the determination of trace arsenic, antimony, bismuth and mercury in geochemical samples law.
