In order to resolve the problem of personal care product being difficult to be dealt with,the paper constructed an undivided electro Fenton system with the reduced graphene oxide (rGO)-doped gas diffusion electrode (rGO/C-PTFE GDE) as cathode to achieve the electrocatalytic oxidation degradation of personal care products (PPCPs)-triclosan. The influence of additive amount of graphene, current densities and electrolyte concentration on electrochemical generation of H2O2 and current efficiency were investigated in detail.The most optimum conditions of producing H2O2 are that the mass ratio of graphene and graphite equals 1:8, current density is 2.0 mA/cm2, electrolyte concentration is 0.05 mol/L.The accumulation concentration of H2O2 electrode after 180 minutes reaches 187.1 mg/L under which conditions. The homogeneous electro-Fenton oxidation system was constructed to degrade triclosan simulation wastewater. The influences of electrolyte pH and Fe2+ concentration on the removal rate of triclosan were investigated. The triclosan of 73.9% of can be removed under the optimal conditions of pH 3.0 and 0.75 mmol/L Fe2+ electrolyzed after 180 minutes.
