Degradation of Remazol Brilliant Blue KN-R by Microwave-Assisted Fenton Method Based on Response Surface Optimization

Taking Remazol Brilliant Blue KN-R as the degradation target, the microwave-assisted Fenton degradation method was optimized by a single factor and response surface methodology. The concentration of FeSO₄·7H₂O, the dosage of 30% H₂O₂, pH value, microwave temperature and microwave time were investigated, and the process conditions were optimized by the response surface analysis. When the concentration of Fe²⁺ was 0.10 mmol/L, the dosage of 30% H₂O₂ was 1.74 mL/L, the microwave power was 222 W, the microwave time was 6 min, and the standing time was 40 min, the results showed that the decolorization rate of Remazol Brilliant Blue KN-R could reach 95.26%.
