摘要
铅经硝酸溶解，使用电感耦合等离子体原子发射光谱仪（ICP-AES）测定银含量，加标回收率87．1％～118．4％，测定相对标准偏差（RSD）≤3．81％。方法简便，测定速度快，结果准确，适用于铅及铅合金中银的检测。
After the sample was dissolved by nitric acid, silver in lead pig was determined by ICP - AES to obtain the addition standard recovery of 87.1% - 118.4% and relative standard deviation of ≤3.81%. This method is simple, fast, accurate and suitable for detection silver in lead and lead alloy.
