ABSTRACT
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.
