Abstract
In this study, Fe-Al binary oxide was synthesized and evaluated for arsenic removal. Due to its large surface area, Fe-Al mixed oxide shows four times higher As(V) and As(III) adsorption capacity than conventional iron oxide. For a comparative study, single metal oxides such as iron oxide and aluminum oxide are also synthesized. The physical and chemical characteristics of the prepared adsorbents are analyzed by SEM, XRD, and BET analyzer. Through the adsorption isotherm and pH effect experiments, it is discovered that Fe-Al binary oxide shows excellent arsenic adsorption capacity compared with single metal oxides.
