Background: The use of (advanced oxidation processes) AOPs, due to have high performance in degradation of organic compounds is growing. Combined use of electrical current and sulfate free radical creates a synergy effect on removal of pollutant. The aim of this study was to evaluation the performance of activated per sulfate by the electrochemical method with copper – iron electrodes for removal of Aniline from aqueous solution.Materials and Methods: In this experimental study, a batch electrochemical reactor with a useful volume of 250 mL, copper and iron electrodes with 2×10×50 mm area from the DC source to aniline degradation was used. Also the Influence of parameters such as pH, Voltage (with amper), initial concentration of per sulfate and initial concentration of Aniline was investigated. Aniline concentrations, determined by spectrophotometer DR5000 making HACH.Results: The experimental results indicated that the removal of aniline was influenced by different operational parameters, So that the highest process efficiency was obtained at pH 4, a voltage of 11 V, a concentration of per sulfate anions equal to 750 mg /L and a concentration of 60 mg /L of pollutant, 90.41% in a 25 minute period. It was also found that with an increase of nitrogen gas, efficiency will be increase and aeration reduces efficiency.Conclusion: The present study demonstrated the proper performance of the process in removing organic pollutants under optimal conditions of use as well as an alternative technology for the treatment of industrial wastewater containing Aniline.
