Study on the degradation of p-chlorophenol in water by using high frequency ultrasound |

| Abstract: | The reaction processes and mechanism of the degradation of p chlorophenol using high frequency ultrasound (1.7 MHz) were investigated in detail in this paper. The degradation effect was studied and some primary influencing factors such as the initial concentration were discussed. The results show that the degradation of p chlorophenol is a first order reaction and the degradation mechanism is mainly based on ultrasonic cavitation. |
