AbstractWe have developed a chemical analysis method for platinum group elements and gold. We start by fusing rock samples with sodium peroxide. After reduction with stannous chloride, PGE and Au are extracted by coprecipitation using selenium and tellurium as carriers. Yields approach 100%. The analysis is carried out by ICP-MS to improve detection limits. Instrumental operating conditions, mass interference, internal standards, and calibration are discussed. The results obtained for international standards are generally in good agreement with the proposed values. The method presented here can be used for samples that are either poor or rich in PGE and Au and is currently been used for PGE and Au determinations in mafic and ultramafic rocks.
