Various affecting factors of methyl orange in the presence of nanometer TiO2 powder prepared in laboratory on ultrasonic degradation have been studied. The results indicate the effects of ultrasonic degradation are more obvious in the presence of nanometer TiO2 catalyst in the acidic condition irradiated with the ultrasound of 25 kHz frequency and power output of 50 W for about 80 min and the ratio of degradation can get to 98.6% and COD removal rate reaches 99.0% too.Thereby the ultrasonic degradation of organic pollutants catalyzed by nanometer TiO2 catalyst has better applicable prospect.
Key words: nanometer titanium oxide; ultrasonic degradation; methyl orange
