Description:
The electro-Fenton (EF) process is a promising method combining electrochemical reactions and Fenton's reagent. In this hybrid process, the electrical current induces the in situ generation of H 2 O 2 via reduction of oxygen, and the catalytic reaction is propagated by Fe 2+ regeneration, which can take place by reduction of Fe 3+ with H 2 O 2 , hydroperoxyl radical, organic radical intermediates, or directly at the cathode. Recent advances in the EF process are discussed and several key variables analyzed, including electrode material, initial pH, and Fenton's reagents, in order to extend the applicability of this technology. A brief survey of the electro-Fenton (EF) process for the removal of different pollutants is presented. Special attention is focused on improving the technology by optimization of the fundamental variables governing the process, including pH, electrode material, and identity of Fenton's reagents in order to extend the applicability of this process.
