AB  - Since 2,4-dichlorophenol (2,4-DCP) as a priority pollutant is used in numerous 
      industrial processes, its removal from the aqueous environment is of utmost 
      importance and desire. Herein, the authors describe an electrochemical treatment 
      process for efficient removal of 2,4-DCP from aqueous solutions using 
      electro-Fenton (EF) process. Response surface methodology (RSM) was applied to 
      optimize the operating parameters. Analysis of variance (ANOVA) confirmed the 
      significance of the predicted model. The effect of independent variables on the 
      removal of 2,4-DCP was investigated and the best removal efficiency of 98.28% 
      achieved under the optimal experimental condition including initial pH of 3, 
      H(2)O(2) dosage of 80 muL, initial 2,4-DCP concentration of 3.25 mg L(-1), current 
      density of 3.32 mA cm(-2), and inter-electrode distance of 5.04 cm. The predicted 
      removal efficiency was in satisfactory agreement with the obtained experimental 
      removal efficiency of 99.21%. According to the obtained polynomial model, 
      H(2)O(2) dosage revealed the most significant effect on degradation process. The 
      kinetic investigation revealed that the first-order model with the correlation 
      coefficient of 0.9907 and rate constant (K(app)) of 0.831 min(-1) best fitted 
      with the experimental results. Generation of the hydroxyl radicals throughout the 
      EF process controlled the degradation process.
