Abstract

Fe₂O_s/γ-Al₂O₃ catalyst was prepared by impregnation method and characterized by powder X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and test results show that, Fe203 crystal was compounded on γ-Al₂O₃ carrier. Fe₂O₃/γ-Al₂O₃/H₂O₂ and Fe₂O₃/γ-Al₂O₃/H₂O₂ /UV processes were tested and optimized to remediate organic material of phenol. An initial phenol concentration of 250mg/L was used as representative of a phenolic industrial wastewater. The experiment optimized the effects of preparation conditions on behaviors of Fe₂O₃/γ-Al₂O₃ catalyst and the processes to degrade phenol in aqueous environments. The experimental results showed that the removal of phenol with Fe₂O₃/γ-Al₂O₃/H₂O₂ /UV was more complete than with Fe₂O₃/γ-Al₂O₃/H₂O₂ and degradation of phenol can reach 94.7% after the reaction for 2 h.
