This chapter presents the degradation and mineralization of emerging trace contaminants artificial sweeteners (ASs) in aqueous solution by electro-Fenton process in which hydroxyl radicals were formed concomitantly by OH formed from electrocatalytically generated Fenton’s reagent in the bulk solution and M(OH) from water oxidation at the anode surface. Experiments were performed in an undivided cylindrical glass cell with a carbon-felt cathode and a Pt or boron-doped diamond (BDD) anode. The effect of catalyst (Fe2+) concentration and applied current on the degradation and mineralization kinetics of ASs was evaluated. The absolute rate constants for the reaction between ASs and OH were determined. The formation and evolution of short-chain carboxylic acids as well as released inorganic ions, and toxicity assessment during the electro-Fenton process have been reported and compared.
