| Abstract: | The simultaneous determination of Ag, Cu, Fe, Pb, Bi and Sb in gold ingot by flame atomic absorption spectrometry（FAAS） was proposed. The detection limits for Ag, Cu, Fe, Pb, Bi and Sb were 0. 008, 0. 020, 0. 015, 0. 032, 0. 22 and 0. 25 μg/mL. The recoveries for six elements were between 94% - 108% and the relative standard deviations were less than 1.8% , the method is rapid, and convenient accurate. |
