摘　　要：采用ICP-AES法对7B50铝合金中锌、镁和铜的测定进行了研究,着重进行了基体元素及待测元素在测定浓度范围内的线性相关性试验,进行了酸度试验,测定了7B50铝合金中3种元素的含量,得到了较好的精密度和准确度。方法简便、可靠,获得满意的分析结果。The method of determination of Zn, Mg and Cu in 7B50 Al alloy by ICP-AES is proposed. The interference experiment between the matrix and co-exist element in 7B50 Al alloy were carried and the linear equation of the calibration curve were studied. The acid effect on the element Zn, Mg and Cu were studied. The method is rapid and reliable with high precision and accuracy.
