| 摘 要： | 制备了光催化剂纳米ZnO,并对催化剂进行表征,探讨了超声协同纳米ZnO光催化氧化降解亚甲基蓝的影响因素.结果表明:与单一超声法(US)、单一光催化氧化法(UV+ZnO+O2)相比,超声协同光催化氧化法(US+UV+ZnO+O2)对亚甲基蓝的降解效果显著;在超声功率为200 W、催化剂用量为2.0g/L、亚甲基蓝溶液的初始浓度为10mg/L、光照时间100min时,亚甲基蓝溶液的降解率可达92%以上.

| Abstract: | Nano-ZnO was prepared and characterized.The factors of photocatalytic degradation of methylene blue by nano-ZnO with ultrasound wave were studied.Results showed that the US+UV+ZnO+O2 system had better degradation effect on methylene blue compared with US system and UV+ZnO+O2 system.The photocatalytic degradation rate of methylene blue was over 92% at the ultrasonic power of 200 W,the amount of catalyst 2.0 g/L,the concentration of methylene blue of 10 mg/L,and the time of photocatalytic degradation of 100 min. |
