The optimum operating variables to achieve 70removal of COD, 80removal of colour and 80 removal of NH 3-N were: H2O2/CODmolar ratio 3.75, H 2O2/Fe2+molar ratio 10.5 and irradiation time 1.5 h. There was good agreement (\< 2error) between experimental removal efficiency andmodel prediction. The characteristics of the photo-Fenton treated leachate were: NH3-N 112 mg/L, colour 108 Pt-Co Unit, COD350mg/L, BOD5 116mg/L andBOD5/CODratio 0.33, indicating that the treated leachatewas amenable to biological treatment. The study has revealed thatRSMis an effective tool to optimize the treatment process and photo-Fenton is an effective pretreatment ofmature landfill leachate for biological treatment.}, issn = {09726268}, author = {Heng, G.
