摘要

采用超声辅助萃取-固相萃取-分散液-液微萃取（SPE-DLLME）-气相色谱-火焰离子化检测器（GC-FID）分析相结合的新预处理方法，测定了蔬菜样品中二嗪农的含量。使用超声波辅助提取、固相提取和分散液-液微萃取从花园欧芹样品中提取分析物。已经优化了影响提取技术效率的各种参数。校准图在5.0–1000范围内呈线性 μg kg−1，检测限为1.0 μg kg−1，用于花园欧芹样品中的二嗪农。结果证实了UAE-SPE-DLLME-GC-FID作为分析花园欧芹样品中目标分析物的灵敏方法的适用性。

Development of ultrasound-assisted extraction followed by solid-phase extraction followed by dispersive liquid–liquid microextraction followed by gas chromatography for the sensitive determination of diazinon in garden parsley as vegetable samples

A new pretreatment method termed ultrasound-assisted extraction (UAE) which is combined with solid-phase extraction which is combined with dispersive liquid-liquid microextraction (SPE-DLLME) followed by gas chromatography-flame ionization detector (GC-FID) analysis has been developed for the determination of diazinon in garden parsley as vegetable samples. The analyte was extracted from garden parsley sample using ultrasound-assisted extraction followed by solid-phase extraction followed by dispersive liquid-liquid microextraction. Various parameters that affect the efficiency of the extraction techniques have been optimized. The calibration plot was linear in the range of 5.0–1,000 μg kg−1 with detection limit of 1.0 μg kg−1 for diazinon in garden parsley samples. The results confirm the suitability of the UAE-SPE-DLLME-GC-FID as a sensitive method for the analysis of the targeted analyte in garden parsley samples.
