Ultrasonic destruction of chlorinated compounds in aqueous solution

Abstract

Abstract The application of ultrasonic‐wave energy for the destruction of low concentrations of carbon tetrachloride into nonhazardous end products is described, and the results of experimental work are presented. Process parameters studied included steady‐state temperature, concentration, pH, irradiation time, and the intensity of the applied ultrasonic‐wave energy. Greater than 99% destruction efficiencies were achieved through this process, and the irradiation time required for a given degree of destruction decreased with increasing intensity of the ultrasonic energy. In addition, a detailed chemical reaction mechanism for the destruction of carbon tetrachloride in water was formulated. The agreement between the model and experimental results is generally good.
