A new method for the determination of pentachlorophenol(PCP) in human urine has been developed by headspace solid-phase microextraction with gas chromatography(HS-SPME-GC).A homemade ionic liquid(IL) bonded coating solid-phase microextraction was added by the sol-gel method.The extraction conditions were optimized as the extraction temperature of 80℃,extraction time of 50 min by headspace,desorption time of 5 min at 300℃,NaCl amount of 3 g,pH of 2 and under stirring.The detection limits was 5.0 ng/L.The linear range was 0.05-100 μg/L.The relative standard deviations(RSD) was 5.9%.The recovery was 106.6%.
