Abstract A method for arsenic(Ⅲ) and arsenic(Ⅴ) speciation in water samples using HG-AFS was established. Without any preseparation technique, the speciation was simply accomplished by just adjustment of the acidity for hydride generation. For a sensitive,reproducible and accurate determination, other conditions for hydride generation, such as the concentration of NaBH4 and the added amount of KI as the reductant for arsenic(Ⅴ), were also optimized, and the interference experiment was carried out for concomitant elements. As a result, a detection limit of 0.026 μg·L-1,a relative standard deviation of 2%, and a recovery of 97.5%-103.0% were obtained，indicating the robustness of the method.
