In order to improve the sonocatalytic activity of TiO2, Al2O3/TiO2, Y2O3/TiO2 and Fe2O3/TiO2 composites were prepared using mechanical mixing, liquid boiling, ultrasonic dispersion and heat-treated methods. And then, a series of degradation experiments were carried out under ultrasonic irradiation. Also, the influences of heat-treated temperature and heat-treated time on the sonocatalytic activity of Al2O3/TiO2, Y2O3/TiO2 and Fe2O3/TiO2, and ultrasonic irradiation time and solution acidity on the sonocatalytic degradation of Acid red B were investigated by UV-vis spectra. It was found that the degradation ratio showed significant increase in the order TiO2 < Fe2O3/TiO2 < Y2O3/TiO2 < Al2O3/TiO2. And the corresponding percentage degradations are about 37, 45, 52 and 81%, respectively. In addition, for exploring the universality, the degradation of other several organic dyes was also reviewed under the same conditions. Because of good degradation efficiency, this method may be an advisable choice for the treatment of non- or low-transparent wastewaters in the future.
