摘　　要：报道用小试金-光谱法同时测定地质试样中痕量Pt、Pd、Rh、Ir的方法。将10-20g试样中的Pt、Pd、Rh、Ir富集在毫克量的金合粒中,然后用发射光谱法同时测定痕量Pt、Pd、Rh、Ir。A method for emission spectrometry determination of trace Pt, Pd, Rh and Ir in geological samples was reported in this paper. Pt, Pd, Rh and Ir in the samples of 10 ~ 20g were preconcen-trated by fire assay in gold alloy particles of a few milligram. Trace Pt, Pd, Rh and Ir in the samples were then determined simultaneously by emission spectrometry.
