| Abstract | ||||
| FENTON'S reagent is a mixture of ferrous iron catalyst and …….hydrogen peroxide, used for oxidation of organic compounds in acidic medium. As the pH increases, the iron ions precipitate and diminish the oxidative efficiency of Fenton reaction. We selected different chelating agents [glutamic acid (Glu), citric acid (CIT) and sodium citrate (SC)] that form Fe-chelates soluble in neutral pH (Modified-Fenton) for studying its effect on phenol degradation. The results revealed that the rate of degradation by Glu, CIT and SC iron chelates were 73, 60 and 77%, respectively, in short term experiments (3hr). In the long term experiments (24hr), the degradation was increased to 82, 72 and 86%, respectively. | ||||
