| Abstract: | The degradation effect of p-nitrofluorobenzene in aqueous solution by Ultrasound-Fenton reagent technology and the major affecting factors such as the sound intensity,pH value of solution,initial concentration and medium temperature were studied.The results showed that the degradation mechanism mainly based on the free radicals oxidation and that ultrasound-Fenton reagent technology was superior to ultrasound irradiation alone degrading p-nitrofluorobenzene.Within half an hour,the sum of PFNB removal rate as using ultrasonic irradiation and Fenton reagent oxidation respectively to degrade PFNB was obviously over the removal rate by using Ultrasound-Fenton reagent technology.The synergetic effect of Ultrasound-Fenton reagent technology was obviously significant. |
