摘    要:本方法对有机氯农药及相关化学品在稻草中残留量的测定方法进行了研究,建立起一个快速均质提取,固相萃取(SPE)净化富集,高效毛细管柱色谱分离,选择离子扫描,质谱定性定量的残留分析方法。通过对提取净化、色谱和质谱条件的优化研究,18种有机氯农药及相关化学品的样品添加回收率为76.09%~106.68%(n=5),相对标准偏差(RSD%)为1.57%~9.11%,浓度在0.005~0.8μg/mL范围内残留性良好,相关系数为0.9987~0.9973,最低检出限为0.0008~0.008mg/kg。

关 键 词:稻草  有机氯农药  化学品  残留量  GC-MS

Abstract:The paper studies determination method of organochlorine pesticides and related chemicals multi-residues in the straw.Multi-organochlorine pesticides and related chemicals residues in the straw were determined by GC-MS equipped with a high performance capillary column chromatography,selected ion scan MS qualitative and quantitative.The straw samples were extracted by fast homogeneous,then were cleaned with SPE.The good linearities were obtained for 18 organochlorine pesticides and related chemicals in the range of 0.005~0.8μg/ml.The correlation coefficient of standard curves was from 0.9987 to 0.9973.The limits of detection were from 0.0008 to 0.008mg/kg.The average recoveries for those pesticide residues in straw were from 76.09 to 106.68%(n=5) at three spiked levels,the relative standard deviations(RSD) were 1.57~9.11%.
Keywords:Straw  Organochlorine pesticides  Chemicals  Residue  GC-MS
