In order to find the best electrolysis conditions for 4-Chlorophenol degradation, adopted response surface methodology (RSM) and central composite design (CCD) to investigate the current density, electrolyte concentration, initial pH and reaction time. A basic quadratic equation for the degradation efficiency of 4-chlorophenol was expressed as a function of individual variables. The results indicated that the linear effects and the quadratic effects of the individual variables (R-2 reached 0.8062 and 0.8230 and was close to 1) were statistically significant. The model provided the optimized conditions as follows: the initial pH was 7.00, electrolyte (Na2SO4) concentration was 0.02 mol/L, the current density was 23 mA/cm(2), and the reaction time was 120 min. The degradation efficiency of the cathodic compartment was more than 95.4%, while anodic compartment's degradation efficiency was 91.1%. Ultimately, 4-chlorophenol was efficiently degraded under the synergistic effect of reduction and oxidation in the present system.
