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 pe roxide and determined by a double focusing high resolution inductively coupled p lasma 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 interna tional reference materials were in agreement with the certified values.
