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FeSO_(4)·7H_(2)O浓度、30%H_(2)O_(2)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FeSO_(4)·7H_(2)O物质的量浓度为0.10 mmol/L、30%H_(2)O_(2)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%.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 FeSO_(4)·7H_(2)O,the dosage of 30%H_(2)O_(2),pH value,microwave temperature and microwave time were investigated,and the process conditions were optimized by the response surface analysis.When the concentration of Fe^(2+) was 0.10 mmol/L,the dosage of 30%H_(2)O_(2)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%.
