Behavior of a Ti/RuO2 anode in concentrated chloride medium for phenol and their chlorinated intermediates electrooxidation

▶ Phenol and its intermediate compounds in NaCl solution were electrooxidized. ▶ Increasing amounts of NaCl favors phenol and their intermediates electrooxidation. ▶ Treated solution contained less than 0.002% of the initial phenol concentration. ▶ The energy consumption for total COD removal was 34.41 kWh kg−1.
