摘要
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 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.
