摘　　要：文章提出一种硫酸中铅、铁、汞、砷含量的新测定方法,采用ICP-AES来测定硫酸中的铅、铁、汞、砷元素,并且做了条件试验,加入已知量元素进行回收试验、精密度试验以及方法比对,此方法快速便捷、测定准确可靠,相对标准偏差为4.9×10^(-5)%~5.3×10^(-5)%,加标回收率为97.33%~102.38%,测定范围0.0001%~0.0090%。A new method for the determination of arsenic,lead,iron and mercury in sulfuric acid was proposed.Inductively coupled plasma emission spectrometer was used to determine arsenic,lead,iron and mercury in industrial sulfuric acid,and the condition test,precision test,standard recovery test and method comparison were done.The method was fast and convenient,accurate and reliable.The relative standard deviation is 4.9×10^(-5)%~5.3×10^(-5)%,the recovery rate is 97.33%~102.38%,and the determination range is 0.0001%~0.0090%.
