dc.description.abstractTHE DEGRADATION OF A HIGHLY LOADED ECF (ELE- MENTAL CHLORINE FREE) KRAFT MILL EFFLUENT WAS STUDIED AND OPTIMIZED USING A CATECHOL (CAT) DRIVEN FENTON REACTION IN A LAB-SCALE FOR 2 H AT ROOM TEMPERATURE USING A RESPONSE SURFACE METHODOLOGY BASED ON A CIR- CUNSCRIBED CENTRAL COMPOSITED DESIGN (CCC). OPTI- MAL COD REMOVAL WAS ACHIEVED AT: CATECHOL 150 ?M.; FE(III) 800 ?M; H 2 O 2 12000 ?M ; PH 2.5. AT THESE OPTIMAL REACTION CONDITIONS, TOC (TOTAL OR- GANIC CARBON), AOX (ADSORBABLE ORGANIC HALOGENS) AND ACUTE TOXICITY WERE DETERMINED AS WELL. COD, TOC, AND AOX REMOVALS ACHIEVED BY THE CAT DRIVEN FENTON REACTION WERE SIMILAR TO THOSE OB- TAINED BY CONVENTIONAL AND FENTON TYPE REACTIONS (40% REMOVALS, MEAN VALUE, IN ALL CASES). HOWEVER, THE ACUTE TOXICITY INCREASED DURING THE CAT DRIVEN FEN- TON REACTION AND THE CONVENTIONAL AND FENTON TYPE REACTIONS. THESE RESULTS SUGGEST THAT THE CAT DRIVEN FENTON REACTION WOULD BE A MORE SUITABLE METHOD FOR EFFLUENT OXIDATION (AS A TERTIARY TREATMENT). FOR A FEA- SIBLE APPLICATION, WE SUGGEST TO IMMOBILIZE CAT, OR TO USE IT AS A SOLID PHASE WITH ANCHORED CATECHO
