This study aims to evaluate arsenic adsorption efficiencies over various metal oxides (CeO2, TiO2, Fe3O4, ZrO2, AlOOH, SiO2, α-Al2O3, and γ-Al2O3) and investigate the correlation between physico-chemical characteristics of metal oxides and their efficiencies. From XPS, XRD BET analysis and isotherm adsorption test, TiO2 powder showed that the best adsorption efficiency, and it's mechanism was highly depended on the chemical adsorption.
