摘要
目的：一次性检测金银花中18种有机磷农药的残留量。方法：以丙酮为提取溶剂，超声提取10min，固相萃取为前处理方法，配有脉冲式硫磷检测器（PFPD），HP-1701毛细管柱的气相色谱仪检测。结果与结论：18种农药能够在30min内完全分离，最低检测限为4．0～18．0μg·kg^-1；对18种有机磷农药在金银花中的添加回收率在83．64％-88．65％，RSD2．8％-6，0％，符合多种农药残留的分析要求。
Objective： To establish an analysical method for the quantitative determination of 18 kinds of organophosphate pesticide residues in Flos Lonicerae. Method： The pesticides in samples were extracted with acetone by Ultrasonic wave Assistant Extraction（UAE）, purified by Solid-Phase Extraction（SPE）. Using PFPD detecter gas chromatography with HP-1701 column. Result and Condution： All 18 pesticides were separated well in 30 minutes. The detection limits was 4.0-18.0μg·kg^-1. The range of recovery and RSD were 83.64%- 88.65% and 2.8%-6.0%, respectively. And it met the requirements of pesticide multi-residues analysis.
