摘要
建立了快速测定萝卜中定虫隆残留方法。样品经乙腈提取,用高效液相色谱仪进行测定。实验结果表明,方法的最低检出量为1×10-9g,最低检出质量分数为0.02mg/kg,在0.1、0.5、1.0mg/kg三种添加水平下,添加回收率范围为85.16%～95.29%,变异系数范围为3.00%～7.53%。该分析方法快速、准确、灵敏,重现性好,适用于萝卜中定虫隆残留量的检测。
For effective detecting of chlorfluazuron residue in radish, a quick analytical method was developed. After extracted by acetonitrile, the target compound was determined by HPLC. The results suggested that the lowest detection limit for chlorfluazuron was 1 × 10^-9g, and the limit of quantification was 0.02 mg/kg. The recoveries of chlorfluazuron from radish spiked with 0.1, 0.5, 1.0 mg/kg ranged from 85.16 to 95.29%, with the coefficient of variation of 3.00 to 7.53%. This method is rapid, accurate, sensitive, and of good reproducibility. It can be used to determinate chlorfluazuron in radish.
