| 摘 要： | 以二氯甲烷-丙酮（体积比1∶1）为混合溶剂，用加速溶剂萃取仪萃取土壤样品中的阿特拉津，提取液通过凝胶渗透色谱净化，用高效液相色谱仪在220 nm波长下测定，试验表明，在0．05 mg/L～5．00 mg/L范围内线性良好。方法检出限为0．22μg/kg，对空白土壤进行加标回收，平行测定6次，平均回收率为88．2％～102％，RSD为4．5％～7．6％，符合农药残留分析的要求。

| Abstract: | The soil sample was extracted with the solution of dichloromethane /acetone（1∶1） using acceler-ated solvent extraction （ ASE ） , and the extracts were purified by gel permeation chromatography （ GPC ） .The concentrated sample was determined by high performance liquid chromatography （ HPLC ） in the 220 nm wave-length.According to the result,the linear range was from 0.05 mg/L to 5.00 mg/L, and the limit of detection was 0.22 μg/kg.The average recoveries were from 88.2%to 102%, and the relative standard deviations were from 4.5%to 7.6%（n=6）.The results could satisfy the requirement of pesticide residue analysis . |
