摘要
以超声波作用制备的Fe3+掺杂TiO2纳米管作为光催化剂,氙灯模拟紫外光为光源,降解活性艳红X-3B,探讨了超声预处理时间、催化剂煅烧温度、pH值、催化剂加入量等因素对活性艳红X-3B降解率的影响,结果表明,超声波预处理时间为20min,催化剂煅烧温度为400℃,pH为强酸或强碱,催化剂加入量为1.0g/L时对活性艳红X-3B处理效果较好。
Degrade the reactive of brilliant red X-3B by photocatalytic processes of.ultrasonic wave-Fe3+ Doped TiO2 nanotubes with xenon lamp simulated as the ultraviolet light source. The influence of ultrasonic pretreatment time, the calcining temperature, pH value of the solution and the catalyst were studied. The result showed that the best photocatalytic activity was observed in TiO2 with 20rain of ultrasonic pretreatment when plt was strong acid or alkali, and the optimum dosage of catalyst TiO2 was 1g/L.
