The adsorption of oxyanions, P(V), As(V), Se(IV), Mo(VI), and Cr(VI), on the synthetic hydrated oxides of iron and aluminum was studied. The absorption sequence of the oxyanions was in the order of As(V), Se(IV) > Mo(VI) > P(V) >Cr(VI) on the goethites, hydrons ferric oxide and hydrous aluminum oxide, and P(V) > Mo(VI) > As(V) > Se(IV), Cr(VI) on the gibbsites. The amount of absorption of the oxyanions on the hydrated oxides of iron and aluminum was larger in the amorphous hydrous oxides than in the crystalline ones. Ligand exchange took place between oxyanions and OH or OH_2 coordinated on the hydrated oxides of iron and aluminum during the absorption. The OH_2 ligand exchange mainly occurred at pH 5.5 for the absorption of As(V), Se(IV), and P(V) on the amorphous hydrated oxides of iron and aluminum.
