| Summary: | IIn this study, the Electro Coagulation (EC) was used for the removal of acid orange 5 from synthetic wastewater in a batch electrochemical reactor. The impact of the operational variables such as current density, initial pH, time of electrolysis, and initial concentration of the dye was investigated. The results showed that the optimum conditions were obtained at initial pH of 7, current density at 2 mA/cm2, 60 mg/lit of Acid orange 5 and time of reaction at 60 min. At optimum conditions, the removal efficiency of acid orange 5 and Chemical Oxygen Demand (COD) were 99.3 and 85.5%, respectively. The kinetic study showed that the removal reaction was first order and the rate constant and half-life of reaction were obtained. |
