| Abstract: | The effects of ultrasonic power, addition of oxidant H_2O_2 and Fenton reagent on the degradation efficiency of 2,4-dinitrophenol by ultrasonic-wave treatment (US) were studied. The degradation of 2,4-dinitrophenol by US, US/H_2O_2 and US/Fe~(2 )/H_2O_2 respectively fitted first-order kinetics. It was found that the degradation of 2,4-Dinitrophenol by US can be enhanced by addition of Fe~(2 )/H_2O_2 mixture. However, the similar synergic effects were not observed for the degradation of 2,4-dinitrophenol when CuSO_4/H_2O_2 was added in ultrasound wave system. |
