| 摘 要： | 采用250 W的金属卤化物灯为光源，在自制纳米Cu2O粉末悬浮体系中，以甲基橙为降解对象，研究了影响甲基橙光催化降解的各种因素，确定了最佳反应条件。结果表明，甲基橙溶液质量浓度为10 mg·L－1、Cu2O加入量为3 g·L－1和pH为5时，甲基橙降解率可达94.58%,添加少量30%H2O2可提高甲基橙降解率，其最佳投加量为15 mL。

| Abstract: | Photocatalytic degradation of methyl orange using nanoparticle Cu2O as the catalyst was studied. Methyl orange degradation rate of 94.58% was attained under the optimal condition as follows： methyl orange concentration 10 mg·L^-1 , Cu20 dosage 3mg·L^-1 and pH =5. Methyl orange degradation rate was enhanced by adding a small amount of 30%H2O2, with optimal amount of 30%H2O2 of 15 mL. |
