Abstract: Degradation of phenol irradiated with a xenon lamp was studied in the presence of sodium oxalateFenton reagent. Effects of light, the initial concentrations of H2O2、C2O2-4、Fe2+ and pH value on the reactions were investigated. The result shows that C2O2-4 can effectively intensify the effect of the Fenton reagent, and under the following conditions, that is, pH=4.0, c(H2O2)=0.735 1 mmol/L, c(Na2C2O4)=0.074 63 mmol/L, c(Fe2+)=0.053 6 mmol/L, the degradation rate of phenol with a mass concent ration of 0.595 2 mmol/L was 76.5% under simulated sunlight irradiation for 90 min and the degradation course obeyed the one order kinetic equation.The main intermediates were also identified by GCMS,and they were organic acid and benzoquinone.
Key words: phenols, photodegradation, Fenton reagent
