研究了反应体系初始pH值、超声波频率、超声波输出功率对超声催化TiO2降解偶氮染料甲基橙的影响。结果表明:初始pH值为1.0左右,超声频率为25kHz,功率为55W时甲基橙降解效果最佳。
In this paper,the effect factors of the ultrasonic degradation of MO with TiO2 as catalyst were studied,such as the beginning pH of solution, the ultrasound frequency and power.The result showed that the degradation of MO was the best when the beginning pH was 1.0,the ultrasound frequency was 25kHz ,the power was 55w.
