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

  • 摘要: 以活性艳蓝KN-R为降解目标, 通过单因素和响应面法优化了微波辅助Fenton法降解工艺. 探讨了FeSO4·7H2O浓度、30% H2O2投加量、溶液酸度、微波功率、反应与静置时间等因素对脱色率的影响, 并利用响应面法优化了脱色条件. 结果表明, 在FeSO4·7H2O物质的量浓度为0.10 mmol/L、30% H2O2加入量为1.74 mL/L、溶液pH值为3.8、微波功率为222 W、微波时间为6 min、静置时间为40 min时, 活性艳蓝KN-R脱色率可达95.26%.

     

    Abstract: 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%.
