Determination of Ag,Cu,Fe,Pb,Sb and Bi in High Purity Gold Ingot by Rapid Extraction-Flame Atomic Absorption Spectrometry

快速萃取-火焰原子吸收光谱法测定金锭中Ag、Cu、Fe、Pb、Bi、Sb,可极大地缩短分析时间,方法的检出限Ag、Cu、Fe、Pb、Bi、Sb分别为0.007、0.016、0.012、0.022、0.10、0.10μg/mL;回收率在94.0%—106.0%之间;RSD小于1.7%。方法快速、简便、准确。

The simultaneous determination of Ag,Cu,Fe,Pb,Bi and Sb in gold ingot by rapid extraction-flame atomic absorption spectrometry（FAAS） was proposed.The detection limits for Ag, Cu,Fe,Pb,Bi and Sb were 0.007,0.016,0.012,0.022,0.10,0.10μg/mL,respectively.The recoveries for 6 elements were between 94%-106%and the relative standard deviations were all less than 1.7%.The method is rapid,convenient and accurate.
