A novel purge-assisted and temperature-controlled headspace solid-phase microextraction (PATC-HS-SPME) couple to gas chromatography-negative ion chemical ionization mass spectrometry (GC-MS-NCI) method was developed for the determination of six pyrethroids, including fenpropathrin,-cyhalothrin, cypermethrin, flucythrinate, fenvareate and deltamethrin, in aqueous samples.The method is based on the continuous nitrogen gas through the hollow fiber and purging into the heated sample to carry analysts to the headspace that the temperature is controlled by a cooling circulate system.The purpose of this work was to develop a rapid, simple, efficient, economical and environmental friendly method for the simultaneous extraction of 6 synthetic pyrethroids in water samples.
