A fast and simple method, which involves dynamic liquid-phase microextraction followed by gas chromatography with flame ionization detection, has been developed to facilitate the identification and quantification of three phthalate esters (dimethyl phthalate (DMP), diethyl phthalate (DEP), and di-n-butyl phthalate (DnBP)) in water samples. Experimental parameters affecting the extraction efficiency, such as extraction solvent, solvent volume, dwell time and extraction frequency were investigated. Under the optimal conditions, the method yields ...
