Abstract

The traditional electro-Fenton process is unable to treat alkaline organic wastewater effectively. An alkaline electro-Fenton process has been proposed on the basis of H₂O₂ synthesis in the KHCO₃ electrolyte using an In₂O₃ film anode and H₂O₂ activation into ˙OH via MnO₂ powder, which could overcome the deficiencies of the traditional electro-Fenton process.
