Abstract :In this study, the investigation of 4-clorophenol insert ignore into journalissuearticles values(CP); removal from aqueous solutions using copper electrodes by electrocoagulation insert ignore into journalissuearticles values(EC); process was done. The effects of various experimental parameters such as pH, current density and exposure time, which affect the EC process, on 4-CP removal were investigated. To optimize the process, response surface methodology insert ignore into journalissuearticles values(RSM); Box Behnken Design was used by MINITAB program, a series of experimental sets were obtained and carried out. Afterward, 4-CP removal was analyzed and calculated. Results were entered into the MINITAB program as a response. At the end of the optimization, optimum operating conditions were determined as 74 mA/cm2, 45 min, 4.24 for current density, exposure times and pH, respectively. When the results were evaluated, approximately 92% phenol removal efficiencies were obtained. Additionally, according to the model results, it was understood that the factors with the greatest effect on 4-CP removal were the exposure time and current density and these had a linear effect, but the pH value did not have a significant effect.
