摘　　要：文中应用电感耦合等离子体发射光谱法对纯金中的杂质元素抛、Cu、Fe、Pb、Sb、Bi测定进行了研究，Ag、Cu、Fe、Pb、Sb、Bi的检出限分别为：0．0038，0．0030，0．0046，0．0093，0．0115，0．0272μg／ml，回收率均在98．9％-103．1％，10次测定的精密度小于4％，结果令人满意。A research on the measurement of impurity element in pure gold, such as Ag, Cu, Fe, Pb, Sb and Bi, was carried out with ICP-AES method. The detection limit of Ag, Cu, Fe, Pb, Sb and Bi was respectively 0. 003 8, 0. 003 0, 0. 004 6, 0. 009 3, 0. 011 5 and 0. 027 2μg/ml, while the recovery rate was 98.9% - 103.1%. And the precision is less than 4% in 10 times measurement. The results are satisfiable.
