Preparation of Iron Catalysts Generated from Fe-Coagulated Sludge Produced by Ferric Chloride Coagulation of Wastewater

Abstract:

In this work, the Fe_xO_y catalysts were prepared by the co-precipitation method. The catalysts were characterized by X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS), and Brunauer-Emmett-Teller (BET) surface analysis. From XRD results, the Fe_xO_y with the wastewater to coagulant ratio of 1:2 catalyst (Fe_xO_y-1:2) calcined at 600 °C for 6 h showed the presence of the wustite (FeO) form. XANES analysis showed the phase of FeO in Fe_xO_y-1:2 calcined at 600 °C for 6 h which corresponded to the result from XRD. The Fe_xO_y 1:1 catalyst had higher specific surface area and larger total pore volume compared to the Fe_xO_y 1:2 catalyst.
