Phenolic compounds are hazardous industrial wastes that can contaminate real water resources. Therefore, the removal of these compounds in order to reach acceptable levels before discharging becomes challenging. In this study, a combination method between dispersive liquid-liquid microextraction (DLLME) with high-performance liquid chromatography-UV detection at 280 nm with the isocratic condition was introduced as a new approach for separating phenol content in water samples. The optimized parameters that affect the extraction efficiency, such as type of solvents, the volume of extraction and dispersive, stirring speed of centrifuge and salt concentration were evaluated using response surface methodology (RSM). A central composite design (CCD) was used to investigate the effect of four independent variables parameters, as mentioned. The recovery value on the DLLME method for the water sample is in the range of 92.31 - 114.29%. Based on the recovery obtained, the DLMME-HPLC-UV is a promising method for phenol extraction because it is simple, effective and produce a high percentage of the recovery.
