Abstract: Due to the high electrical costs associated with the implementation of AOPs during water pollution treatment, alternative sources of energy to power the systems are required. In this work, the feasibility of the use of a photovoltaic array to supply the electrical power needs of the UV-A/Fe2+/H2O2 system for degrading a natural water with 12 and 3 μg/L of anthracene and benzo[a]pyrene, respectively, was studied. It was found that more than 99% and 30% of the studied compounds and the organic matter were converted, demonstrating the performance of the oxidation system from photovoltaic energy.
