摘要
文章设计了原子荧光光度法同时测定食用盐中铅、砷的新实验方法。新方法铅检出限为0.008 8 mg/kg,RSD≤1.2%,平均回收率为103.4%。砷检出限为0.001 0mg/kg,RSD≤0.7%,平均回收率为97.6%。此方法操作简单,结果准确,非常适合食用盐中铅、砷的测定。
A new trial method of HG- AFS for the simultaneous determination of lead and arsenic in edible salt was studied. The detection limit of lead was 0. 008 8 mg /kg,RSD was less than 1. 2% and the average recovery was 103. 4%. The detection limit of arsenic was 0. 001 0mg /kg,RSD was less than 0. 7% and the average recovery was 97. 6%. This method was simple,accurate and extremely suitable for the determination of lead and arsenic in edible salt.
