Resumen
ZN-EDTA DEGRADABILTY BY CATECHOL-DRIVEN FENTON REACTION WAS STUDIED. RESPONSE SURFACE METHODOLOGY CENTRAL COMPOSITE DESIGN WAS EMPLOYED TO MAXIMIZE THIS COMPLEX DEGRADATION. THEORETICAL SPECIATION CALCULATIONS WERE IN GOOD AGREEMENT WITH THE EXPERIMENTAL RESULTS. FENTON AND FENTON TYPE TREATMENTS ARE TYPICALLY THOUGHT TO BE APPLICABLE ONLY IN THE HIGHLY ACIDIC RANGE, REPRESENTING A MAJOR OPERATIONAL CONSTRAINT. INTERESTINGLY, AT OPTIMIZED CONCENTRATIONS, THIS CAT-DRIVEN FENTON REACTION AT PH 5.5 ACHIEVED 100% ZN-EDTA DEGRADATION; 60% COD AND 17% TOC REMOVALS, USING TINY AMOUNTS OF CAT (50 ?M), FE(III) (445 ?M) AND H2O2 (20 MM) WITH NO EVIDENT FERRIC SLUDGE.
