摘要
以硝酸处理试样 ,利用锌基体对石墨炉原子吸收法测定砷的改进作用 ,无须加入其它改进剂 ,标准加入法直接测定锌锭中的砷 ,该法检出限为 0 3 6μg/L ,回收率为 93 %～ 10 5 %。
The sample was dissolved by HNO3, and the matrix zinc was used as the modifier for the determination of arsenic in zinc ingots by GFAAS. The standard addition method was adopted The detection limit of this method is 036μg/L for arsenic The recovery is in the range of 93%-105%.
