Abstract: Mineralization of a 5 mM EDTA solution at pH 3 was evaluated via TOC removal under UV-C irradiation in the presence of H(2)O(2) at various conditions. The highest TOC removal (78%) was obtained using a 40:1 H(2)O(2)/EDTA molar ratio, after 540 min irradiation. However, a 20:1 ratio gave slightly lower results, being economically more attractive. Best results of TOC removal were obtained under pH controlled conditions. Addition of TiO(2) (1 g l(-1)) was detrimental, even in the presence of H(2)O(2), indicating that at this concentration, TiO(2) inhibits the mineralization, probably by scattering or by screening of the light.
