| 摘 要： | 用实验室合成的Gd2O3掺杂TiO2为催化剂，以甲基橙超声降解反应为模型，研究了各种因素对Gd2O3掺杂TiO2催化超声降解甲基橙的影响。研究结果表明，Gd2O3掺杂TiO2催化超声降解甲基橙的效果明显优于非掺杂的锐钛矿型TiO2的情况；在甲基橙溶液pH1．0～3．0、甲基橙质量浓度20mg／L、溶液用量100mL、催化剂用量0．5～1．0g／L的条件下，用输出功率1．0W／cm^2和频率25kHz的超声波照射60min，甲基橙降解率可达98．6％，COD去除率可达99．0％。

| Abstract: | The various affecting factors were studied on ultrasonic degradation of methyl orange in the presence of Gd_2O_3-doped TiO_2 catalyst prepared in laboratory.The results indicate that the effects of ultrasonic degradation are more obvious in the presence of Gd_2O_3-doped TiO_2 catalyst than in the presence of pure anatase TiO_2 catalyst.Under the conditions of solution pH 1.0-3.0,methyl orange mass concentration 20 mg/L,solution volume 100 mL,catalyst dosage 0.5-1.0 g/L,irradiation power 1.0 W/cm~2,frequency 25 kHz,and irradiation time 60 min,the degradation rate of methyl orange can come up to 98.6% and the removal rate of COD to 99%. |
