摘要/Abstract

摘要： 以活性艳橙溶液为模拟废水,通过H₂O₂/TiO₂超声(US)协同作用光降解活性艳橙溶液,探讨了TiO₂催化剂用量、H₂O₂用量、活性艳橙溶液的初始浓度、pH值、TiO₂催化剂锻烧温度等对活性艳橙溶液降解率的影响,并比较了几种不同作用方式对活性艳橙溶液的降解效果.结果表明:UV/H₂O₂/TiO₂/US协同作用降解活性艳橙溶液的效果最好;当活性艳橙溶液的初始浓度为20 mg·L^-1,pH＝5,TiO₂用量为0.4 g·L^-1,H₂O₂用量为0.4 ml·L^-1时,降解率可达92.06%.

Abstract: Reactive brilliant orange as simulated wastewater,it was synergistic action of H₂O₂/TiO₂/ultrasound that degrades the solution.The effect of initial concentration of reactive brilliant orange,dosage of TiO₂ and H₂O₂,pH and TiO₂ calcination temperature on the degradation efficiency of reactive brilliant orange were investigated,and compared several different function ways to the degeneration effect of reactive brilliant orange. The result shows that the synergistic degradation of reactive brilliant orange with UV/H₂O₂/TiO₂/US is the best.When initial concentration of reactive brilliant orange is 20 mg·L^-1,pH value is 5,TiO₂ concentration is 0.4 g·L^-1,H₂O₂ concentration is 0.4 mL·L^-1,the degradation rate of reactive brilliant orange is 92.06%.
