Though the ultrasonic/H2O2 process shows potential application for wastewater treatment

there were only a few reports on degradation kinetics. In this paper

the synergetic kinetics of phenol degradation in water by using ultrasonic/H2O2 system was studied. It was found that phenol degradation followed pseudo-first order reaction under individual ultrasonic radiation or H2O2 process

while it was significantly enhanced in the combined ultrasonic/H2O2 system. This indicated that there exist synergetic effects in the ultrasonic/H2O2 process and it was found that the enhancement factor for phenol degradation rate constant was about 6.904. A simplified mechanistic model for phenol degradation was derived by accounting for the contribution of individual ultrasonic radiation

H2O2 oxidation and hydroxyl radical in the combined ultrasonic/H2O2 system. The model was proved to be well suitable for the phenol degradation in the presence of surplus H2O2.
