研究了微波-Fenton试剂氧化联合使用对甲基红染料废水的降解.考察了联合工艺中最佳微波功率、反应时间与不同浓度甲基红对反应的影响因素.利用紫外分光光度计对处理前后甲基红浓度进行测定.结果表明:300～450W的功率梯度范围下,300W,反应20min,降解效果最佳,最大降解率为55％.然后在300W的功率下,改变时间,得到时间越长,降解率越高,但最大降解率无明显变化.引入Fenton试剂与微波对甲基红废水协同降解,协同降解的效果较好,模拟废水变为近乎无色,且试管底部有明显沉淀.说明超声波-Fenton氧化法具有一定协同作用.“,”The joint treatment of microwave irradiation and Fenton reagent oxidation was applied to methyl red used as a proxy for dyeing wastewater.The effects of optimal microwave power,reaction duration and methyl red concentration were investigated.The UV spectrophotometer was employed to determine the concentrations of methyl red before and after the treatment.The experiment results demonstrated that given a reaction duration of 20min,a microwave power of 300W performed best when compared to other powers in the range 300～450W,yielding a maximal degradation rate of 55％.Moreover,for microwave power fixed at 300W,the degradation rate improved as the reaction duration prolonged,albeit with no apparent impact on the maximal degradation rate.However,when Fenton reagent and microwave irradiation were utilized in conjunction,the synergistic degradation on methyl red solution was relatively good:the solution became mostly colorless with apparent precipitation at the bottom of the test tube,which indicating that the ultrasonic-Fenton oxidation method has a certain synergistic effect.
