Abstract

The influence of operational parameters and anode materials on degradation kinetics, mineralization current efficiency, and energy consumption for electrochemical oxidation of phenol was studied. Phenol elimination follows pseudo‐first‐order kinetics in most cases except for the Ti/RuO~2~ anode with a phenol concentration of 500 mg L^–1^, where pseudo‐zero‐order kinetics is observed. The total organic carbon removal by a Ti/Sb‐SnO~2~ anode follows pseudo‐first‐order kinetics in contrast to pseudo‐zero‐order kinetics by Pt and Ti/RuO~2~ anodes. For a certain anode, a higher current or voltage input results in a higher reaction rate. With a Ti/Sb‐SnO~2~ anode, the highest current efficiency and the lowest energy consumption are obtained, but the current efficiency decreases (increases for energy consumption) quickly as the reaction is prolonged due to the reduction of organics.

The promoted wet air oxidation of phenol has been investigated through the addition of hydrogen peroxide as a source of free radicals. The reaction has been shown to proceed in two stages, an initial fast reaction associated with hydrogen peroxide consumption and a second slower step that occurs at
