Study on Decolorization of Reactive Violet K-3R by Microwave-Fenton Reaction

The decolorization process of reactive violet based on the microwave-assisted Fenton reaction has been studied. The experimental results showed that the combination of microwave and Fenton method can bring good synergistic effect. When the pH of the active violet solution was 4, the dosage of 30% hydrogen peroxide was 0.6 mL/L, and the concentration of ferrous sulfate was 0.3 g/L, the decolorization rate of the active violet can reach up to 98.13% after being exposed to 400 W microwave irradiation for 3 min and standing for 25 min.
