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.
