Arsenic is a toxic substance. The adsorption by activated carbon is generally considered to be one of the most efficient methods to remove As(V). In this paper, three kinds of commercial activated carbons (N1, N2 and N3) were used to adsorb As(V) from water. The result showed that the adsorption capacity of As(V) on N1, N2 and N3 were 2.539 mg / g, 1.014 mg / g and 0.581 mg / g, respectively. N1 had an advantage of adsorption capacity for arsenic. Besides, the effect of ferrous(Fe2+) and chloride(Cl-) ion on the adsorption of arsenate on N1 was investigated. Due to more activated sites being contributed by the adsorptive iron, Fe2+ promoted the adsorption of As(V) on N1. Cl- occupied activated sites to declining the adsorption of As(V) on N1.
