The effect of ultrasonic energy on the degradation of methyl orange is found to be enhanced obviously in the presence of TiO₂ catalyst under the acidic condition. Irradiation with the ultrasound of 25 kHz frequency and power input of 1.0 W/cm² at pH=1.0, 98% methyl orange can be degradated within 90 min.
