摘要
文章探讨了玉米中溴甲烷残留量的检测方法。结果表明:采用酸回流方法提取玉米中的溴甲烷,进行毛细管色谱分离检测,操作简便、结果准确、灵敏度高。在0.29μg/mL～11.78μg/mL范围内,色谱峰面积与浓度有较好的线性关系,标准工作曲线相关系数R2为0.9987,检出限为0.02mg/kg。
This research discussed a method for the determination of methyl bromide residues in corn by gas chromatography. The result shows that： using acid circumfluence and capillary chromatogram detection, This method was shown to be simple, sensitive and precise .Linear plots were obtained in range of 0.29μg/mL～11.78μg/mL withy the limit of detection（LOD）being of 0.02 mg/kg. And the correlation coefficient of standard analysis curve is 0.9987.
