Electrochemical Advanced Oxidation Processes (EAOPs) are promising technologies for environmental remediation. These processes are based on the high oxidation power of hydroxyl radicals. This radical is a strong oxidant with high reactivity to degrade organic pollutants present in liquid effluents. Hydrogen peroxide (H2O2) can be electrogenerated in the system by reducing two oxygen electrons on the surface of carbonaceous cathodes, allowing the generation of homogeneous hydroxyl radicals in the reaction medium, increasing the process efficiency. This project aims to evaluate the synergistic effect of the H2O2 in carbon-supported electrocatalyst materials and their application in the treatment of synthetic and real solutions containing endocrine interferences using different EAOPs, such as electrochemical oxidation with electrogeneration of H2O2, electro-Fenton, photo electro-Fenton and solar fotoelectro-Fenton. The processes used will be compared by optimizing some parameters such as: anodic material, applied current density, electrolyte support, amount of iron added and pollutant concentration, to achieve the most viable process. The costs of the processes will be taken into account in order to verify the economic viability of the researched treatment. Finally, all results will be correlated with the existing data in the literature to highlight what was achieved during the work. (AU)
