This study investigated the availability of TiO₂ photo-catalysis for the aqueous-phase oxidation of Ethylenediaminetetraacetic acid (EDTA). The tendency of EDTA adsorption onto the catalyst surface was affected by the TiO₂ surface charge, and the oxidation rate of EDTA by photo-catalysis was shown to depend upon the tendency of EDTA adsorption before photo-irradiation. Oxygen enhanced the photooxidation rate of EDTA. The photooxidation rates of EDTA were determined for initial EDTA concentrations ranging from 0.89 mM to 8.91 mM. The experimental data showed that the photooxidation process of free-EDTA followed Langmuir-Hinshelwood kinetics.
