The conditions for membrane preparation was investigated. Its physicochemical properties were evaluated by infrared spectrum, thermogravimetric analyse and electron microscope.. The extraction time, desorption time and ion strength of solution were optimized. The linear range of the method was 25～1000 μg/L, the detection limit was ～ μg/L, and the relative standard deviation(RSD)was %～ %. This method is suitable for the determination of phthalate esters in water sample.57 / 6
