建立了用气相色谱分析蜂蜜中溴虫腈的方法。样品经溶解、固相萃取净化,用气相色谱测定,外标法定量。该方法快速、准确,在0.01~0.50 mg/L范围内线性相关系数R2=0.9996,平均回收率达到95.7%~98.1%,相对标准偏差为1.3%~2.4%,最低检测浓度为2.010-4 mg/kg。

[Abstract]
A new method for the determination of chlorfenapyr in honey by solid-phase extraction and gas chromatography was described here. The method was fast and accurate with a linear correlation of 0.9996 in the range of 0.01 to 0.5 mg/L. Its average recoveries were within the range from 95.7% to 98.1% and the relative standard deviation ranged from 1.3% to 2.4%. Besides, the minimum determination concentration was shown to be 2.0×10-4 mg/kg.
