FENOL'ÜN FOTOKİMYASAL YÖNTEMLERLE PARÇALANMASI VE MİNERALİZASYONU

In this study, photochemical advanced oxidation processes (AOPs) utilizing the combinations of UV, UV/H2O2 and UV/H2O2/Fe 2+ were investigated in lab-scale experiments for the degradation and mineralization of phenol. The major parameters investigated were the initial phenol concentration, pH, hydrogen peroxide and iron doses. The results of this study showed that UV irradiation alone can degrade phenol but at very slow rates, however, cannot mineralize the compound. The addition of hydrogen peroxide to the system, so-called the UV/H2O2 process significantly enhances phenol degradation rate but still requires relatively long reaction periods for complete mineralization. The Photo-Fenton process, produces the highest photochemical elimination rate of phenol degradation and complete mineralization is possible to achieve in quite shorter reaction periods when compared with UV/H2O2
