Abstract

The amounts of arsenic,selenium and mercury in environmental water were determined by AFS. The standard series method for sample solution and the effect of hydrochloride and potassium borohydride were studied. The instrument conditions were optimized. The detection limit for As,Se and Hg are 0. 51μg/L,0. 53μg/L and 0. 065μg/L with the RSD of 1. 51%,2. 36% and 1. 63%. The recovery are 90. 0%-105. 0,92. 0%-97% and 90. 0%-97. 5%,respectively.
