摘要
以茅台酒厂2010年生产酒糟为样品,利用干法灰化进行前处理,采用原子吸收分光光度法测定样品中Mn、Cu、Fe、Pb的含量。结果表明,该方法简单易行,方便快捷,结果准确,样品中Mn、Cu、Fe、Pb的平均含量分别为43.03 mg/kg、8.35 mg/kg、373.70 mg/kg和5.63 mg/kg酒糟,该方法的加标回收率为101.0%～107.8%,相对标准偏差小于2.00%。
Distiller＇s grains produced in Maotai Distillery in 2010 underwent dry ashing and then the content of Mn,Cu,Fe,Pb in the samples were determined by FAAS.The results showed that such method was simple and rapid to operate and could achieve accurate measurment results.The average content of Mn,Cu,Fe,Pb in per kg distiller＇s grains were 43.03 mg/kg,8.35 mg/kg,373.70 mg/kg and 5.63 mg/kg respectively.The recovery of such method was 101.0 %～107.8 % and the RSD was less than 2.00 %.（Tran.by YUE Yang）
