摘    要:提出了毛细管气相色谱测定人血清中有机氯农药残留量的方法。利用正己烷超声提取人血清样品中有机氯农药六六六和滴滴涕,所得萃取液作气相色谱测定,用甲酸及浓硫酸净化、磺化处理后,电子捕获检测器检测。在优化的试验条件下,8种有机氯农药同分异构化合物组分在20 min内能够很好的分离,其质量浓度与色谱峰面积在0.4~10μg·L~(-1)浓度范围内呈线性关系,检出限(3S/N)在0.07~0.30μg·L~(-1)之间。方法的日内的相对标准偏差为2.9%~5.4%,日间的相对标准偏差为4.5%~8.9%。方法的加标回收率在81.5%~117.6%范围。

关 键 词:气相色谱法  毛细管柱  人血清  有机氯农药残留

Abstract:Gas chromatography with capillary column was applieed to the determination of residual amounts of organochlorine pesticides in human serum.The sample was diluted with formic acid and extracted with n-hexane ultrasonically.The upper organic layer was taken and sulfonated with conc.H_2 SO_4.The sulfonated solution layer was separated and evaporated to near dryness in a vacuum dryer.The residue was taken up with 1 mL of n-hexane and used for GC analysis,with electron capture detector.Four isomers each of the p...
Keywords:Gas chromatography  Capillary column  Orgaochlorine pesticide residues  Human serum
