dc.description.abstractThe photocatalytic degradation of EDTA solutions (5 mM) has been studied under different conditions in the presence of TiO2 in suspension or immobilized on glass rings and in the absence and presence of Fe(111). Using the response surface methodology, the initial pH, amount of photocatalyst, and the Fe/EDTA molar ratio were optimized in order to obtain better degradation. Under optimized conditions, 90% EDTA degradation (at a 0.28 Fe/EDTA molar ratio) was reached after 60 min illumination at pH 3.0 and using 0.73 g L-1 TiO2. Increase of the acute toxicity (Microtox) was observed in the course of the reaction, and degradation intermediates were identified by GC/MS analysis. (c) 2005 Elsevier B.V. All rights reserved.pt
