Abstract

For the first time, lepidocrocite-granular activated carbon (γ-FeOOH-GAC) nano composite was prepared and characterized. The prepared composite was used in the decolorization of textile wastewater containing reactive orange 29 by photo Fenton-like process in a continuous reactor. The influence of wastewater flow rate, H₂O₂ concentration and pH in decolorization process was studied using response surface methodology. The optimum conditions were flow rate of 1.98 mL min^-1, H ₂O₂ concentration of 3.25 mM and pH of 1.98. The decolorization ability of γ-FeOOH-GAC/H₂O₂/UV process was compared with that of γ-FeOOH-GAC/UV, γ-FeOOH-GAC/H ₂O₂, γ-FeOOH-GAC, H₂O₂/UV, and UV processes at the optimum conditions. The obtained results indicated that γ-FeOOH-GAC/H₂O₂/UV process was more effective than other processes in the decolorization of the wastewater.
