| Abstract: | The degradation effect of p-chlorophenol in aqueous solution by ultrasound-hydrogen peroxide technology and the major affecting factors such as the sound intensity, pH value of the solution, initial concentration and free radicals scavenger were studied in this paper. The results showed that the degradation mechanism was mainly based on the free radicals oxidation and that ultrasound-hydrogen peroxide technology was superior to ultrasound irradiation alone in degrading p-chlorophenol and TOC. |
