Abstract:Iron (III) vanadate catalysts were prepared by a hydrothermal method under different acid-base. The obtained samples were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM) and Fourier Transform infrared spectroscopy (FTIR). The as-prepared samples were used as Fenton-like catalysts on the degradation of Rhodamine B (Rh B) which was used as a model pollutant. The effects of pH value, H2O2 concentration, iron (III) vanadate concentration and the type of iron (III) vanadate on the heterogeneous Fenton-like degradation of Rh B were investigated. The XRD patterns indicate that Iron (III) vanadate samples were FeVO4·1.25 H2O. The decolorization rate of Rh B at 60 min could reach 97% at the optimal operating conditions. The range of pH values which the FeVO4·1.25 H2O was appropriate was found to be much wider than that of the classic Fenton's reagent. Moreover, FeVO4·1.25 H2O samples could be reutilized for the perfect settling performance. The Fenton-like catalysts may have a better prospect of application in wastewater treatment.
