Description:
The photooxidative degradation of 4-nitrophenol (4-NP) was studied in the UV/H"2O"2 process. The effects of applied H"2O"2 dose, initial 4-NP concentration and UV light intensity have been studied. Degradation was complete in 13min and follows apparent first-order kinetics. The removal efficiency of 4-NP depends on the operational parameters and increases as the initial concentration of H"2O"2 and light intensity are increased but it decreases when the initial concentration of 4-NP is increased. From HPLC analysis, major intermediate products were hydroxyl derivatives of 4-NP as a result of photooxidative hydroxylation.
