摘　　要：该研究建立了高效液相色谱串联质谱(HPLC-MS/MS)测定玉米中苯唑氟草酮的检测方法。通过优化QuEChERS条件,使样品得到有效提取和净化。结果表明,苯唑氟草酮在1~100μg·L^(-1)线性关系良好,相关系数大于0.99,方法定量限为6μg·kg^(-1)。在6、20、100μg·kg^(-1)添加水平下,平均回收率为89.0%~90.4%,相对标准偏差为0.8%~2.5%(n=6)。该方法简便、高效、灵敏、准确,适用于玉米中苯唑氟草酮残留的测定。This study established a detection method for fenpyrazone in maize using high-performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).QuEChERS method was optimized for effective extraction and purification of fenpyrazone in samples.The results showed that there was a good linear relationship in the concentration range of 1-100μg·L^(-1) for fenpyrazone with correlation coefficient greater than 0.99.The limit of quantitation(LOQ)was 6μg·kg^(-1).At three spiked concentration levels of 6,20 and 100μg·kg^(-1) for fenpyrazone,the average recoveries were 89.0%-90.4%,with relative standard deviations(RSDs)of 0.8%-2.5%(n=6).The method is simple,efficient,sensitive,accurate and suitable for determination of fenpyrazone in maize.
