In this work, the application of heterogeneous photo-electro-Fenton processes using iron supported on Nafion membranes and ion exchange amberlite and purolite resins is studied. Spectroscopic and TOC results using as a model pollutant an aqueous Orange II dye solution indicate that the process can be carried out with any of the iron supporting materials under study. While the resins can incorporate between 59 and 65 mg Fe/g of substrate, a Nafion membrane can fix 45 mg Fe/g of supporting material. Iron desorption analysis after a photo-electro-Fenton degradation test on the other hand, indicates that the ion exchange resins and the Nafion membrane hold more than 90% of iron. An alkaline rinse after the activation exchange process for the amberlite resin and the Nafion membrane, results in a larger stability of the fixed iron species.
