The photochemical decolourisation of chlorotriazine reactive azo dye Reactive Orange 4 (RO4) has been carried out by Fenton and photo-Fenton processes. The effects of solution pH, applied H2O2, Fe2+ dose, UV light intensity have been studied. The increase of initial dye concentration decrease the removal rate. Under optimum conditions the photo-Fenton process is found to be more efficient than Fenton process. About 2% of colour resurgens was observed at the end of the reaction. (C) 2004 Elsevier Ltd.
