摘要
Abstract
[Objective]To establish determination methodology of pentachlorophenol in fish gall bladder by automatic solid-phase microextraction ( SPME ) with ancillary extraction of supersonic wave and gas chromatography.[Methods]Pentachlorophenol in fish gall bladder was extracted using optimized SPME technology, separated by HP-5 and DB-17 chromatographic columns and the content of pentachlorophenol in fish gall bladder was determined by electron capture detector( ECD )under optimized conditions.[Results]The linear range of the calibration curve was 0.08-100.00 μg/L with a correlation coefficient of 0.9997 and the detection limit for pentachlorophenol was 0.053 μg/L.The recovery rates were between 81.5％-92.6％ and the relative standard deviations were between 3.6％-6.3％.[Conclusion]The method is simple, rapid and sensitive without solvent pollution, which is a ideal method for determination of pentachlorophenol in fish gall bladder.关键词
