摘    要:采用气相色谱双柱法对果汁中多种有机磷类农药残留量进行测定。样品用丙酮提取后,经Carb/NH2 固相萃取小柱净化,用DB-1701、DB-35ms 毛细管气相色谱柱,火焰光度检测器,对果汁中多种有机磷类农药残留量的测定可取得满意的结果。该方法测定样品的平均加标回收率为75.23%~98.53%,相对标准偏差为0.97%~8.16%,果汁中有机磷类农药残留检出限为10~60μg/kg。

关 键 词:果汁  有机磷类农药  残留量  气相色谱双柱法  火焰光度检测器

Abstract:A dual-column gas chromatographic method was developed for the multi-residue determination of organophosphorus pesticides in fruit juice.Samples were extracted with acetone,and the resulting extract was cleaned up on Carb/NH2 SPE cartridge.The chromatographic separation was achieved on DB-1701 and DB-35ms capillary columns.Analytes were detected with FPD.The average recoveries of 6 replicates for analytes in blank samples spiked at 3 levels ranged between 75.23% and 98.53%,with relative standard deviations ...
Keywords:fruit juice  organophosphorus pesticides  multi-residues  dual column gas chromatography  FPD
