QuEChERS-HPLC同时测定蔬果中残留氨基甲酸酯类和苯甲酰脲类农药

摘要

A QuEChERS high performance liquid chromatography (HPLC)method for the determination of carbamate and benzoylurea pesticides in vegetables and fruits was established. The recovery rate of pesticide components is between 70. 5％ and 118.5％, and the relative standard deviation (RSD)is between 2. 6％ and 9. 8％. The detection limit is between 0. 02 ～ 0. 30 mg/kg, meeting the requirements of the national standard for the detection limit. The developed method is rapid, simple, economical and environment-friendly, and is easy to be popularized in local inspection institutions.%建立了采用QuEChERS-高效液相色谱法 (QuEChERS-HPLC) 测定蔬菜水果中残留的氨基甲酸酯类和苯甲酰脲类农药的检测方法.农药组份回收率在70.5％～118.5％之间, 相对标准偏差 (RSD) 在2.6％～9.8％之间, 方法的检出限为0.02～0.30 mg/kg, 满足国标检测限量要求.该方法具有快速、简便、经济、环保的特点, 便于在地方检测机构推广.
