研究Te共沉淀分离富集、ICP-MS铂族元素和金测定方法。方法检出限1～9 pg/g；回收率≥90%。国标GBW07288-GBW07294、加拿大WGB1及南非铂矿SARM7等标样分析表明：结果满意，方法可靠。%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.
