摘要: 建立测定果蔬中己唑醇残留量的气相色谱质谱法。样品用乙腈提取,GCB/NH2固相萃取柱净化,石油醚:丙酮(15:85,V/V)洗脱,DB-5 ms色谱柱分离。己唑醇的检出限为0.02mg/kg,方法的精密度和回收率分别为3.03%~9.34%和92.24%~106.13%。该方法线性关系好,重复性好,准确度高,可为水果蔬菜中己唑醇残留的监测建立确证方法。

Abstract: A gas chromatography-tandem mass spectrometric (GC-MS/MS) method was established for the determination of hexaconazole in fruits and vegetables. Samples were extracted with acetonitrile, and cleaned up on a GCB/NH2 SPE column using a mixture of petroleum ether and acetone at ratio of 15:85 (V/V). The chromatographic separation was carried out on a DB-5 ms column. The limit of detection for hexaconazole was 0.02 mg/kg. The precision RSDs and spike recoveries of the method were separately 3.03%-9.34% and 92.24%-106.13%. The method was highly linear, repeatable and accurate and thus could offer a suitable method for the accurate determination of hexaconazole residue in fruits and vegetables.

Key words: gas chromatography-tandem mass spectrometry, fruits and vegetables, hexaconazole
