摘  要：
[目的]建立了多壁碳纳米管滤过型净化,气相色谱串联质谱技术同时测定香蕉中联苯菊酯等5种拟除虫菊酯类杀虫剂残留量的分析方法.[方法]香蕉样品用乙酸乙酯提取,经多壁碳纳米管滤过型净化柱净化后,用气相色谱-串联质谱法测定.[结果]联苯菊酯等5种拟除虫菊酯类杀虫剂的质量浓度在0.01~0.2 mg/L范围内线性良好,定量限均为10μg/kg,相关系数均大于0.99,平均加标回收率为71.3%~108.3%,相对标准偏差为0.7%~3.6%.[结论]方法学考察及实际样品的测定证明该方法简便、快速、准确,可用于香蕉中联苯菊酯等5种拟除虫菊酯类杀虫剂残留量的检测.

摘  要：
[Aims] A multi-residue method was developed for the simultaneous determination of 5 pyrethroid insecticide residues in banana by using gas chromatography coupled with tandem mass spectrometry(GC-MS/MS).[Methods] The banana samples were extracted with ethyl acetate and cleaned up with multiplug filtration using multiwalled carbon nanotubes,then determined by GC-MS/MS.[Results] The limits of quantitation for 5 pyrethroid insecticides was10 μg/kg.Calibration curves exhibited good linearity over the concentration ranged from 0.01 to 0.2 mg/L,with their correlation coefficients of above 0.99.Average recoveries for 5 pyrethroid insecticides ranged from 71.3 to 108.3%,with relative standard deviations ranged from 0.7 to 3.6%.[Conclusions] Methodological investigation and real samples determination showed that the developed method was sensitive,rapid and accurate.As a result,it can be applied for determination of 5 pyrethroid insecticides residue in banana
