摘    要：研究了铅对原子吸收光谱法测定锑及铜的干扰及其消除方法,提出了测定铅钙合金中锑、铜的新方法.测定锑的特征浓度为0.4 mg/L(1%),线性浓度范围0~30 mg/L;测定铜的特征浓度为0.037 mg/L(1%),线性浓度范围为0~3 mg/L;方法简便快速,选择性好,经标样分析表明,结果的准确度及精密度均符合要求.

Abstract: The interference of lead on the determination of Sb and Cu by AAS was studied, and a new method for determination of Sb and Cu in Pb Ca alloy was established. The feature consistency in determining Sb is 0.4 mg/L(1%), the range of lineal consistency is 0～30 mg/L; the corresponding data in determining Cu is 0.037 mg/L(1%) and 0～3 mg/L. The method is simple, repaid, reproducible, and has been applied to the analysis of standard model of Pb Ca alloy with satisfactory results.
