摘要
建立了两种以火试金预浓集为基础的、可用于准确测定铂族元素的方法 ;中子活化法和电感耦合等离子体质谱法。讨论了它们的分析检出限、准确度及其适应性。并用这两种方法测定了
Two methods for the determination of platinum group elements were established based on neutron activation analysis (NAA) and inductively coupled plasma mass spectroscopy (ICP-MS) combined with fire assay preconcentration. Their analytical sensitivity, accuracy and applicability were discussed. The detection limits (ng/g) of NAA for Ru, Rh, Pd, Os, Ir and Pt are 0.5, 0.5, 0.3, 0. 1, 0.01 and 0.2, respectively, whereas those of ICP-MS are 0.1 for Ru, 0.05 for Rh, 0.1 for Ir and 0.1 for Pt. Thus, both are complimentary for determination of platinum group elements. By the established methods the contents of platinum group elements in five geological reference materials were determined.
