This paper describes the work that has been carried out using neutron activation analysis (NAA) to develop a rapid and reliable method for the determination of the platinum group elements (PGE: Pt, Pd, Ir, Ru, Rh, and Os) and Au in geological, environmental and industrial samples. The method is based on the now established method of preconcentration with fire assay, followed by NAA of the separated PGE and Au. Recent developments have seen improvements in the technique to eliminate losses due to dissolution procedures, and complete recovery of the elements prior to analysis. The method is now being used to validate inductively coupled plasma-mass spectroscopy methods for analysis of the PGE.
