In this study a new dispersive liquid–liquid microextraction (DLLME) method is presented on the basis of a safe organic solvent, octanol, which is lighter than water. The proposed method is used for the extraction and pre-concentration of some preservatives including methyl paraben (Mep), ethyl para
