Degradation of 2,4-dicholophenol, p-tert-butylphenol, and benzophenone was performed by the three methods; electrolysis, photo-irradiated electrolysis and sono-irradiated electrolysis. 2,4-dicholophenol was dissolved in water. p-tert-butylphenol was dissolved in aqueous 30 vol% methanol solution and benzophenone was dissolved in aqueous 50 vol% ethanol solutions since these substance are scarcely soluble in water. The sono-irradiated electrolysis decomposed 2,4-dicholophenol and p-tert-butylphenol faster than the other methods, but these methods were of similar decomposition rate for benzophenone. The effctiveness of sono-irradiated electrolysis decreased in the order of 2,4-dicholophenol, p-tert-butylphenol and benzophenone. Cavitation effects rather than stirring effects of the ultrasounds probably played an important role in the sono- irradiated electrolysis.
