摘  要:
建立了固相萃取(SPE)前处理方法联合气相色谱/三重四极杆质谱(GC-MS/MS)检测蔬菜水果中西玛津、莠去津、嘧霉胺、异丙甲草胺、二甲戊灵、氟虫腈、稻瘟灵、虫螨腈、乙酯杀螨醇、哒螨灵、咪鲜胺、苯醚甲环唑、嘧菌酯共13种农药多残留的检测分析方法。结果表明:13种农药在30 min内实现了良好的分离,在0.01~2.00 mg/L的质量浓度范围内线性关系良好,相关系数>0.998,方法检出限为0.001~0.010 mg/kg。13种农药在0.01、0.10、1.00 mg/L 3个浓度添加水平下,平均回收率在82.9%~111.2%之间,测定值的相对标准偏差(n=6)在1.1%~5.6%之间,能够满足农药多残留的分析要求。

摘  要:
SPE-GC-MS/MS was proposed for the determination of 13 kinds of pesticide residues,including simazine,atrazine,pyrimethanil,metolachlor,pendimethalin,fipronil,isoprothiolane,chlorfenapyr,chlorobenzilate,pyridaben,prochloraz,difenoconazole,azoxystrobin in vegetables and fruits.Results showed that 13 pesticides could be well separated within 30 minutes,and the linear ranges of 13 pesticides were all 0.01 ~2.00 mg/L with the linear relative coefficients more than 0.998 and detection limits in the range of 0.001 ~0.010 mg/kg.Recovery rates at the three concentrat-ions of 0.01,0.10,1.00 mg/L ranged from 82.9% to 111.2%,and RSDs(n=6) were in the range of 1.1%~5.6%,which fitted for the requirements of residue analysis.
