Sonochemical degradation of brilliant green and malachite green has been carried out by ultrasound (4 MHz) in an ultrasonic interferometer. The sonochemical degradation of dyes was observed by spectrophotometric method. The effect of various parameters like pH, concentration of dyes, solvent composition, temperature, nature and concentration of surfactant on the reaction rate of the sonochemical degradation was also observed. The value of energy of activation was also computed for sonochemical degradation. A tentative mechanism has been proposed.
