| Abstract: | The degradation mechanism and processes of p-chlorophenol using high frequency ultrasound were investigated in detail.The degradation effect and its affecting factor such as the initial concentration,advanced oxidation processes and so on were studied.The results show that the degradation of p-chlorophenol is a first-order reaction and the degradation mechanism is mainly based on ultrasonic cavitation,and there will be good prospects for industrial utilization of ultrasound combined with other advanced oxidation processes,which can remarkably increase the degradation efficiency. |

| Keywords: | high frequency ultrasound p-chlorophenol degradation cavitation |
