The photochemical degradation of p-dichlorobenzene on titanium dioxide was carried out in the presence of Fenton's reagent, and progress of the reaction was observed spectrophotometrically. The effects of the variation of various parameters, such as pH, concentration of p-dichlorobenzene, Fe³⁺ ion concentration, amount of photocatalyst, amount of hydrogen peroxide, light intensity etc. on the photodegradation of p-dichlorobenzene were observed. A tentative mechanism for this degradation has also been proposed.
