【Abstract】 A method for the determination of Pt.Pd. Ru. Rh. Ir and Au in geological samples was studied. The sample was fused by sodium peroxide and determined by a double focusing high resolution inductively coupled plasma mass spectrometer "ELEMENT" after the separation and enrichment by co-precipitation with Te. Detection limit of the method was between 1 -9ng/g and the recovery was > 90%. Our analytical results for some domestic or international reference materials were in agreement with the certified values.更多还原
