초록 This study is concerned with the analysis of platinum group metals(PGMs especially Palladium and Platinum) in minerals and materials. PGMs are widely used as catalysts in petroleum and chemical processes. They are found wide applications in exhaust-gas control converters and are of immense importance to the eletronics industry. They are found in many items of jewellery and serve to an increasing extent as a form of investment. PGMs occurs in traces in most minerals and materials. They are extracted in minute quantities from a limited number of ores. They are concentrated and separated from each other by eleborate chemical processes. In this survey, effects of various acid concentration, diverse interfering elements, various decomposition methods were observed for the determination of Palladium and Platinum using standard reference catalyst by ICP-AES. As the results, for the determination of these elements should be separated from matrix elements by separated concentration method. Also in order to confirm specification of samples, major, minor and trace elements in samples should be analyzed by ICP-AES and XRF. All analytical results of Palladium and Platinum in standard reference sample and real samples compare with the NAA. Finally the ralative standard deviations of approximately 1% S are from the precision study using standard reference sample for Palladium and Platinum
