摘　　要：以Al2O3、K2S2O7、NaF、C作为缓冲剂与样品混匀,装入石墨电极中,以平头石墨电极为上电极,样品电极为下电极进行摄谱,由光电译谱仪测定谱线的黑度值,以锗为内标用内标法测定样品中Cu、Pb、Zn、Co、Ag、Sn、Mo和B的质量分数。As buffer with Al2O3, L2S2O7, NaF and C, mix with samples, and put them into graphite electrode tube, the flat graphite electrode means the upper electrode, and sample electrode means the lower one to make spectral analysis ; the blackness value of the spectral lines are determined by the photoelectric interpreting spectrometry. The Ge is as an intetrnal standard, the contents of Cu, Pb, Zn, Co, Ag, Sn, Mo and B in samples are determined by the internal standard technique.
