摘要
用ICP-AES同时测定工业硫酸样品中的铁、砷、铅、汞。方法加标回收率为97%—110%,11次测定的RSD(n=11)小于2.4%。方法操作方便,分析速度快,结果准确。
The amounts of Fe,As,Pb and Hg in sulfuric acid were determined rapidly by ICP- AES. The average recovery is 97 %-110% with relative standard deviation of 0. 3 %-2.40%. The method was applied to the analysis of the samples with satisfactory results.
