中文摘要: 开展待测农药残留样品的高效、快速检测方法研究，建立快速、准确测定蔬菜中有机氯、拟除虫菊酯农药的超声波辅助-气相色谱-质谱检测方法。用气相色谱-质谱检测方法，乙腈作为提取溶剂，超声波辅助提取，CARB/NH2固相萃取小柱净化，通过Rtx-5MS色谱柱分离检测，用外标法对蔬菜10种有机氯和8种拟除虫菊酯类农药残留进行了测定。方法灵敏准确、简便快捷，满足现阶段蔬菜中的农药残留分析要求。
Abstract:The research was carried out for detecting the pesticide residue in samples efficiently and rapidly. The determination of ultrasonic assisted extraction-gas chromatography-mass spectrometry method for organochlorine and pyrethroid pesticides in vegetable was established.10 kinds of organochlorine and 8 kinds of pyrethroid pesticide were extracted with acetonitrile；ultrasonic assisted extraction；purified with CARB/NH2solid phase extraction；separated with Rtx-5MS column，detected with gas chromatography-mass spectrometry by external standard method.The method is sensitive，accurate，simple and fast，and can meet the requirements of pesticide residues in vegetables.
