Abstract

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%.

Key words: ultrasound, titanium dioxide, synergetic effect, reactive brilliant orange, degradation
