Three approaches have been combined in a way that their advantages have been used while reducing their deficiencies. The effects of various empirical parameters such as pH, type and volume of dispersive solvent, the volume of extracted organic solvent, salt concentration, the condition of centrifuge, and mixing time were studied and optimal conditions were achieved by using Mini-Tab software and Respond Surface Methodology (RSM) based upon Box-Behnken Design (BBD) and Desirability Function (DF). Under the optimum conditions, calibration curves were linear in the range of 0.1 to 1000 μgL^-1, limit of detections (LODs) were in the range of  0.06 to 0.34μgL^-1 and r²>0.9916, respectively. The method was also utilized to measure phenol and chlorophenols in various water samples successfully resulted in extraction recoveries ranged from 92.8 to 103.9%. https://icc.journals.pnu.ac.ir/article_6270_3c3fb32911c0325ff39e47598e6b538b.pdf
