Bauxite residues are a mass of industrial wastes derived from aluminum metallurgy. This work provided a simple pyrolysis method to magnetize the bauxite residue to serve as a magnetic adsorbent towards heavy metals removal. The X-ray diffraction patterns and Mossbauer spectrum results confirmed the partial reduction of iron species with an obvious enhancement in magnetization. The magnetized bauxite residue exhibited excellent removal efficiencies for Cu2+, Cd2+ and Pb2+ with maximum adsorption capacities of 219.0 mg g?1, 275.4 mg g?1, and 100.4 mg g?1, which could be quickly separated through a magnet. The adsorption equilibrium data were fitted to the Langmuir isotherm model, while the adsorption kinetics followed a pseudo-first-order model. According to the characterization results, chemical precipitation and sorption was the major mechanism for the removal of Cu2+, Pb2+, and Cd2+. Thus, the magnetized bauxite residue exhibited promising applications for heavy metals removal in wastewater.
