Ultrasound power was supplied with hone type at 20kHz, 400W. Process parameters studied were closed steady-state temperature, concentration, pH, sonication time and flow rate. The decomposition of dichloromethane (methylene chloride) was not affected between 300∼340K and pH 3∼9. Dilute methylene chloride in water was rapidly decomposed by ultrasonic irradiation into carbon monoxide and/or carbon dioxide, hydrochloric acid, free chlorine and water at ambient pressure. Decomposition efficiency was about 30% after 2min of sonication and about 50% after 10min of sonication at 25∼100ppm.
