摘　　要：分别计算了采用HG-AAS和AFS测定铁矿石中的砷的检出限和精密度,并分别测定3个铁矿石标准样品中砷含量,通过比较得出采用HG-AAS和AFS测定铁矿石中的砷得到的结果都接近标准值,达到要求。The determination limit and precision in determining the arseme content in iron ores by HG-AAS and AFS methods were calculated. The arsenic content in three iron ores （ CRMS ） were determined using HG-AAS and AFS respectively. It is eoneluded through comparison that the results by both methods are all near to the standard value, satisfying the requirement.
