摘  要：
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。

摘  要：
A method of simultaneous determining 31 pesticides in wool fiber was established by gas chromatographytandem 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.
