摘    要:以丙酮、二氯甲烷以及乙腈等作为提取剂,比较了国标法和CDFA-MRSM法对水果中有机磷农药的提取效率和回收率,提取液用气相色谱仪-火焰光度检测器进行定性、定量分析。结果表明,采用国标法测定农药的平均回收率为82.3%~90.2%,变异系数为3%~9%;采用CDFA-MRSM法测定农药的平均回收率为79.3%~88.7%,变异系数为4%~11%。说明2种方法准确度与精密度较好,均符合农药残留量分析的基本要求。

关 键 词:农药多残留  气相色谱  有机磷农药  固相萃取

Abstract:A testing method of multiresidue for the analysis of organophosphor pesticides in fruit with different extraction techniques was developed.The method is based on GB/T 5009 and CDFA-MRSM(California Department of Food and Agency-Mulritesidue Screen Method).Residues were determined with gas chromatography and Flame Photometric Detection(FPD).In the result,the recoveries in fruit samples were among 82.3%~90.2% with relative C.V among 3%~9% in GB/T 5009 method,and the recoveries in fruits samples were among 79.3%~88.7% with relative C.V among 4%~11% in CDFA-MRSM method,respectively.Both these methods had good recurrence.
Keywords:Multiresidue  Gas Chromatography  Organophosphor pesticides  Solid phase extraction
