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1~100 μg·L-1线性关系良好,相关系数大于0.99,方法定量限为6 μg·kg-1。在6、20、100 μg·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。

Abstract:

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 1-100 μg·L-1 for fenpyrazone with correlation coefficient greater than 0.99. The limit of quantitation (LOQ) was 6 μg·kg-1. At three spiked concentration levels of 6, 20 and 100 μg·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.
