Abstract:ABSTRACT: In this paper,the samples were dissolved in nitric acid and hydrochloric acid at low temperature, the ICP-AES method is used to determine arsenic and mercury in imported acid mud. The best experimental method is established and the analysis conditions are established. The determination range of arsenic is 0.01%-10% and that of mercury is 0.005% -10%. The relative standard deviation is less than 3%, and the recovery rate is 97%-105%. The method is simple, rapid and accurate, which can fully meet the requirements of the determination of arsenic and mercury in acid mud.
