建立羊毛纤维中31种农药残留同时检测的气相色谱串联质谱(GC-MS/MS)确证方法。选用丙酮＋正己烷为提取溶剂，采用改进的QuEChERS法为净化方法，用GC-MS/MS多反应离子监测模式(MRM)测定，内标法定量。在0.03～15.0 mg/L的质量浓度范围内，各农药相关系数均大于0.9943。每种农药在添加水平为0.02～1.0 mg/kg时(n＝5)，回收率为62.4%～110.6%，相对标准偏差(RSD)为4.5%～13.6%。该方法准确性和重复性好、灵敏度高、操作简便，适用于羊毛纤维中多种农药残留的同时测定。

A method of simultaneous determining 31 pesticides in wool fiber was established by gas chromatography-tandem mass spectrometry (GC-MS/MS). Acetone + n-hexane was used as solvent extraction, improved QuEChERS method was adopted for purifying method. The samples were analyzed using GC-MS/MS multiple reaction monitoring mode (MRM), quantified by the internal standard method. The results showed that in the linear range of 0.03-15.0 mg/L, the correlation coefficients were greater than 0.994 3. The recoveries at the fortified levels of 0.02-1.0 mg/kg (n=5) ranged from 62.4% to 110.6% with the relative standard deviations (RSD) of 4.5%-13.6%. The method was accurate, repeatable, sensitive, simple, and suitable for simultaneous determination of multiple pesticide residues in wool fiber.
