| 摘 要： | 研究了甲基橙等有机染料在太阳光和Fenton试剂联合作用下的降解动力学。采用单因子法考察了硫酸亚铁用量、氧化剂双氧水用量和辐射光源等因素对降解效果的影响。结果表明:在优选实验条件下甲基橙的降解效果较好,有机染料的降解过程符合一级动力学。辐射光源对甲基橙的降解速率影响非常大,降解速率随紫外光强度的增强而加快。太阳光下甲基橙的降解速率常数是室内3～4倍,该反应体系在太阳光利用方面具有一定的应用价值。

| Abstract: | Degradation kinetics of methyl orange and other dyes by Fenton reagent under sunlight was studied.The effects of FeSO4 and H2O2 concentration,radiation source are assessed by adopting the single factor method.Results show that the degradation effect of methyl orange is better under the optimum reaction conditions,and the degradation of methyl orange under sunlight follows the pseudo first-order kinetic model.It has found that radiation source has a great effect on the degradation of organic dye and the degr... |
