摘要:

为建立顶空固相微萃取- 气相色谱质谱法测定苹果中速灭威、异丙威、仲丁威、残杀威、呋喃丹、抗芽威和西维因7 种氨基甲酸酯类农药残留的分析方法,对HS-SPME 萃取条件和GC-MS 条件进行优化。结果表明:在0.005~1mg/L 的质量浓度范围内,各组分线性相关系数为0.996~0.999、RSD(n=5)为3.6%~8.2%,7 种农药残留的方法检出限为0.00016~0.0019mg/kg、加标回收率为94.3%~99.8%。该方法快速、灵敏、准确、试剂用量少,且各项方法学指标符合检测要求,是一种快速检测水果中氨基甲酸酯类农药残留的方法。

Abstract:

A method was developed for the determination of MTMC, MIPC, BPMC, IPMC, furadan, pirimicarb and carbaryl carbamate residues in apples using headspace solid-phase micro-extraction (HS-SPME) coupled with gas chromatography-mass spectrometry. The respective optimal conditions for HS-SPME and GC-MS analysis were determined. All 7 analytes exhibited good linearity over a wide concentration range, with a correlation coefficient ranging between 0.996 and 0.999. The relative standard deviations of precision for 5 replicates were between 3.6% and 8.2%. The limits of detection of the method for a total of 7 analytes were between 0.00016 mg/kg and 0.0019 mg/kg. The method proved to have the advantages of rapidity, sensitivity, accuracy and less reagent consumption and meet the requirements for the determination of carbamate pesticide residues in vegetables and fruits duo to good figures of merit.
