Sonochemical degradation of aromatic compounds was performed by a 200kHz ultrasound sonicator in water. A Langmuir type mechanism was adapted to discuss the reaction kinetics, although a homogeneous solution was used for the degradation experiments. The kinetics model used here is based on the local reaction zone at the interface region of cavitation bubbles, where an extremely high concentration of OH radicals exists. To confirm the proposed kinetics model, the effects of initial concentration of aromatic compounds on the degradation rates were investigated. It was suggested that the degradation of aromatic compounds mainly proceeds inside the local reaction zone of the cavitation bubbles and the hydrophobisity of compounds affect the accumulation amount at the interface region of cavitation bubbles.
