Abstract
Al was incorporated in iron oxide to enhance dye removal capacity (Fe-Al binary oxide). Oxides with different Fe:Al ratios (10:0, 9:1, 7:3, 5:5, 3:7, 1:9, and 0:10) were synthesized and applied for removal of organic dyes. Increase of incorporated Al expanded effective surface area that could contact with dye. The highest dye removal efficiency was achieved by 5:5 and 3:7 Fe:Al ratio. The effects of operation parameters such as solution pH, initial dye, and H2O2 concentration on removal of Acid blue 25 were investigated. Fe-Al binary oxide could be repeatedly used for dye removal without the regeneration process.
