| Bibliography: | Phthalate esters（ PAEs） are commonly used plasticizers and have caused pollution to the environment due to their widespread use. Therefore,many countries have listed such compounds as a priority list of pollutants,and it is of great significance to establish an accurate analysis method for monitoring the pollution of PAEs in water. A method of solid phase membrane extraction combined with ultrasonic wave desortion-gas chromatography-mass spectrometer for analysis of PAEs in water was established in this study.The extraction and desorb conditions were optimized. In this study,the samples were ultrasonic wave desorbed for 7 min at bath temperature of 40℃ and ultrasonic powder of 50%. The detection limits（ S/N 〉3） of this method were between 0. 05 μg/L and 0. 26 μg/L,the recoveries in different matrixes were between 76. 2% and 112. 3%,and the relative standard deviations were below 10%. 22-1125/O6 Phthalate esters;Solid phase membrane extraction;Ultrasonic wave desorption;Gas chromatography-mass spectrometry;Water |
