摘　　要：采用自制分子烙印聚合物固相萃取柱来分离净化实际样品大米中的神经性毒剂降解产物，并用毛细管电泳法进行检测，方法简便，准确、灵敏度高。在０．２～５．０μｇ／ｇ浓度范围内，大米样品中５种神经性毒剂降解产物的标准回归曲线线性关系良好，检出限为０．０５　μｇ／ｇ，方法的ＲＳＤ小于６．２０％。Self-made molecule imprinting polymer-solid phase extraction column was used in extracting nerve agent degadation products in rice. The extraction was then examined by capillary electrophoresis. The method was simple, reliable and sensitive. The calibration curve showed a good linearity for the nerve agent degradation products in rice was in the concentration range of 0.2 similar to 5.0 mug/g and the detection limits were 0.05 mug/g. The RSD of the method was less than 6.2%.
