Sumario:In recent years, new Advanced Oxidation Processes based on the electrochemical technology, the so-called Electrochemical Advanced Oxidation Processes (EAOPs), have been developed for the prevention and remediation of environmental pollution, especially focusing on water streams. These methods are based on the electrochemical generation of a very powerful oxidizing agent such as the hydroxyl radical (?OH) in solution, being then able to destroy organics up to their mineralization. EAOPs include heterogeneous processes like anodic oxidation (AO) and photoelectrocatalysis (PEC) methods, in which ?OH are generated at the anode surface either electrochemically or photochemically, and homogeneous ones like electro-Fenton (EF), photoelectro-Fenton (PEF) and sonoelectrolysis (SE), in which ?OH are produced in the solution bulk. This paper presents a general overview on the application of EAOPs to the removal of aqueous organic pollutants, firstly reviewing the most recent works and then looking to the future. A global perspective on the fundamentals and experimental set-ups is offered, and lab- and pilot-scale experiments are examined and discussed.
