摘要: The determination limit and precision in determining the arsenic 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 concluded through comparison that the results by both methods are all near to the standard value, satisfying the requirement.
