| Abstract: | A new method for rapid determination of pentachlorophenol in human blood by gas chromatography with automatic headspace-solid phase microextraction（SPME） was developed.Pentachlorophenol in human blood was extracted with SPME technology,separated by HP-5 chromatographic column and determined by electron capture detector（ECD） under optimized conditions.The linear range of the calibration curve was 0.05—100μg/L with a correlation coefficient of 0.9997 and the detection limit for pentachlorophenol was 0.02μg/L.The recovery was 86.7%—92.8% and the relative standard deviation was in the range of 3.6%—6.7%.The method is simple,rapid and sensitive without solvent pollution and as a ideal method for determination of pentachlorophenol in organismic samples. |
