摘要
建立了用气相色谱法分析食用植物油中溴虫腈的方法。样品经溶解、萃取后用气相色谱测定，外标法定量。该方法快速、准确，在0．01～0．50mg／L范围内线性相关系数r^2=0．9996，平均回收率达到91．6％～94．5％，相对标准偏差为0．56％～1．15％，最低检测浓度为5．0×10^-4mg／kg。
A method for the determination of chlorfenapyr in edible vegetable oil by gas chromatography is described. The method was fast and accurate with a linear correlation of 0. 9996 in the range of 0.01 to 0.5mg/L, average recoveries of 91.6% to 94.5%, a relative standard deviation of 0.56% to 1.15% and a minimum determination concentration of 5.0 × 10^-4mg/kg.
