摘要: 使用乙腈（含1%乙酸）提取样品中的农药，经N-丙基乙二胺（PSA）粉及碳十八粉混合净化，再经气相色谱-三重四级杆串联质谱分析.建立榛子中70种农药残留同时检测的QuEChERS-气相色谱-串联质谱分析方法.方法结果表明，70种农药在线性范围内（5-100 μg·L-1）相关系数均大于0.9915.方法检出限范围为0.001-1.466 μg·kg-1，方法定量限范围为0.003-4.888 μg·kg-1.当加标水平为75 μg·kg-1时，其回收率在70.00%-94.73%之间，相对标准偏差（RSD）在0.29%-11.80%之间.本方法具有操作简单、快速、灵敏的特点，适用于榛子中农药多残留的检测.

Abstract: To establish a QuEChERS-gas chromatography-tandem mass spectrometric method for simultaneous determination of 70 pesticide residues in hazelnuts. The target pesticides in the hazelnut were extracted with acetonitrile and purified with N,N-diisopropylamino ethylamine primary secondary amine (PSA) and C18, then analyzed by gas chromatography-tandem mass spectrometry. The result implied that all the linear relationships were good with the correlation coefficients all greater than 0.9915. The limits of detection of the method were 0.001-1.466 μg·kg-1, the limits of quantification were 0.003-4.888 μg·kg-1. When the 70 kinds of pesticide residues adding standard level was 75 μg·kg-1, the recovery rates and the relative standard deviation (RSD) of the method were from 70.00%-94.73% and 0.29%-11.80%, respectively. The method is convenient, quick, sensitive, and it is suitable to the analysis of multi pesticide residues in hazelnuts.
