中文摘要：本文开发了一个经济、快速、灵敏的多残留分析方法，该方法采用液相萃取与分散固相萃取法联用进行净化，采用气相色谱串联质谱法进行多残留分析，并应用于对非酒精碳酸饮料（可乐、橘子、柠檬、酒花）中34种多类农药（14种有机氯、8种有机磷农药、10种拟除虫菊酯和2种除草剂）残留的定量检测。程序主要包括在硫酸镁、伯仲胺、C-18存在的情况下，采用二氯甲烷的液-液萃取和分散固相萃取法净化。结果显示：该方法的RSD小于14%，所有农药的检测限和定量限分别在0.001-0.027 μg/L和0.004-0.088 pg/L范围内，定量限水平远低于欧盟规定的限值（水中0.1μg/L），不同非酒精性碳酸饮料农药残留的平均回收率在79-111 %范围内，RSDs不到11%，因此，该方法可应用于监管部门对非酒精性碳酸饮料中MCMR农药残留进行常规性检测。
外文摘要：An economical, rapid, and sensitive multiresidue method using liquid-liquid extraction (LLE) coupled with dispersive SPE (dSPE) cleanup was developed for the quantitative determination of 34 multiclass multiresidue (MCMR) pesticides (14 organochlorines, eight organophosphates, 10 synthetic pyrethroids, and two herbicides) in nonalcoholic carbonated beverages (cola, orange, lemon-lime, and citra) using GC with tandem MS. The procedure mainly involved LLE by dichloromethane and dSPE cleanup in the presence of magnesium sulfate, primary secondary amine, and C-18. The RSD of the developed method was found to be less than 14%. The LOD and LOQ values for all the analyzed pesticides were found in the ranges of 0.001-0.027 mu g/L and 0.004-0.088 pg/L, respectively. The LOQ levels of the pesticides analyzed were found to be well below the recommended limit by the European Union (0.1 mu g/L in water). The mean recoveries of pesticides in different nonalcoholic carbonated beverages (cola, orange, lemon-lime, and citra) were found to be in the range of 79-111%, with RSDs less than 11%. The validation data prove that the method can be acceptable to regulatory agencies for the routine analysis of MCMR pesticides in nonalcoholic carbonated beverages.
