摘要
铅及铅合金样品经硝酸溶解,使用电感耦合等离子体-原子发射光谱仪(ICP-AES)测定铁、铜、镉、锡含量,加标回收率铁82.6%—108.9%、铜93.7%—111.4%、镉87.2%—99.1%、锡90.0%—100.6%,测定相对标准偏差(RSD)Fe≤3.32%、Cu≤4.36%、Cd≤2.16%、Sn≤3.26%。方法简便,测定速度快,结果准确,适用于铅及铅合金的检测。
The lead and lead alloys were digested by HNO3,and the amounts of Iron,Copper,Cadmium and Tin were determined by ICP-AES.The recovery rates are Fe 82.6%—108.9%,Cu 93.7%—111.4%,Cd 87.2%—99.1%,Sn 90.0%—100.6%.The relative standard deviation (RSD) are Fe≤3.32%,Cu≤4.36%,Cd≤2.16%,Sn≤3.26%.The method is simple,rapid,accurate and suitable for lead and lead alloys examination.
