Degradation of Orange IV Catalyzed by Fe/S/GAC in the Presence of H₂O₂

Abstract:

A new heterogeneous Fenton-like catalyst of Fe/S/GAC was prepared by granular activated carbon (GAC) soaked in solution of (NH₄)₂S₂O₈ and Fe(NO₃)₃. The effect of the concentration of (NH₄)₂S₂O₈ , Fe(NO₃)₃, drying temperature and different catalysts on the catalytic reactivity of catalyst was discussed. The removal rate of Orange IV was used to express the catalytic reactivity of the catalyst. The prepared catalysts were characterized by X-ray diffraction (XRD), specific surface area (BET) and scanning electron microscopy (SEM). The removal rate of Orange IV followed second-order kinetics. The catalyst of Fe/S/GAC has higher catalytic activity than that of Fe/GAC.
