本文提出了用ＩＣＰ－ＡＥＳ法测定马口铁中的痕量铅。试样用ＮａＯＨ－Ｈ２Ｏ２溶解镀层。测得四种样品的含铅量在０．１４～０．３８μｇ／ｃｍ２范围内。方法的回收率为９６．１％～１０３．２％。方法的精密度（ＲＳＤ）为２．６％～３．８％。本法简便迅速，测量结果的准确度、精密度满足分析要求。
This paper presents the determination of trace lead in tinplate by ICP-AES. Sample with NaOH-H2O2 dissolved coating. The four samples were found to contain lead in the range of 0.14 to 0.38 μg / cm2. The recoveries of the method ranged from 96.1% to 103.2%. The precision of the method (RSD) was 2.6% ~ 3.8%. This method is simple and rapid, the accuracy of the measurement results, precision to meet the analysis requirements.
