摘　　要：报道了用铅试金(留铅灰吹)-光谱法同时测定地质试样中痕量Pt、Pd、Rh、Ir、Os和Ru的方法研究。本方法将10～50g试样中的Pt、Pd、Rh、Ir、Os和Ru富集在7～35g铅扣中,然后通过留铅灰吹得到4～5mg铅金合粒,用发射光谱法可同时测定痕量Pt、Pd、Rh、Ir、Os和Ru。A method for determination of PGM (Pt,Pd,Rh,Ir,Os and Ru) in geological samples was developed by using Pb fire assay and atomic emission spectrometry(AES). It included the preconcentration of PGM 10～50g samples into 7～35g Pb-Au alloy and the cupellation to obtain Pb-Au button. Finally, the PGM elements were determined simultaneously by AES.
