| 摘 要： | 本文建立了以弗罗里硅土为分散剂、乙酸乙酯＋正已烷（V/V,1/9）为洗脱剂提取大蒜中十一种有机氯农药的基质固相分散法（MSPD）,通过研究固相分散剂的净化效果和洗脱剂的极性,优化了方法的条件,并以气相色谱-质谱联用选择离子扫描方式进行检测。对建立的方法进行了评价,结果表明：11种有机氯农药的定量下限（S/N=10）在0.015-0.0.3mg/kg之间,在加标水平为0.25μg/mL和2.5μg/mL时,添加样品的回收率在76.6%-108.6%之间,相对标准偏差在1.2%-10.6%之间。 |

| Abstract: | A method based on matrix solid-phase dispersion （MSPD） extraction with florisil was developed to determine pesticide residues of 11 organochlorines in garlic. Different solid-phase and eluting solvent were investigated. The proposed analytical method was evaluated. The results show that the recovery rate range is 75%-110% with relative standard deviation lower than 10.6%, the LOQ of the 11 organochlorines is between 0.015 and 0.03mg/kg. |
