Self-made molecule imprinting polymer-solid phase extraction column was used in extracting nerve agent degradation 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 ～5.0 μg/g and the detection limits were 0.05μg/g. The RSD of the method was less than 6.2%.
