| 摘 要： | 建立了电感耦合等离子体原子发射光谱(ICP-AES)法测定锌锭中的Pb、Cd、Fe、Cu、Sn 5种杂质元素的方法。样品用硝酸(1+1)溶解后,在稀硝酸介质中利用电感耦合等离子体原子发射光谱仪测定其中Pb、Cd、Fe、Cu、Sn的含量,测定的相对标准偏差(RSD,n=3)小于1.7%,对锌光谱标样BYG0505的测定结果与标准值基本一致。实现了对锌锭中多种杂质元素的简便、快速、准确的同时测定。

| Abstract: | In this article, we determined the concentrations of lead(Pb), cadmium(Cd), iron(Fe), copper(Cu) and tin(Sn) in zinc ingots by inductively coupled plasma atomic emission spectrometry(ICP-AES). The samples were dissolved by nitric acid(1+1), and then the above-mentioned elements were measured in diluted nitric acid medium. The relative standard deviations(RSDs, n=3) were all less than 1.7%. The determination results were consistent with those of the certified reference materials of zinc (BYG0505). With this proposed method, multiple impurity elements in zinc ingots can be simultaneously analyzed with good accuracy and fast speed. |
