| Abstract: | Analytical method of organic phosphoric pesticide in Chinese cabbage was studied by MAE/ GC The types and dosage of extracting solvent, the time and temperature of microwave radiation were optimized by orthogonal design. The detection limit was 0. 0015 -0. 0072 mg/kg. The synthesized sample of 0. 5 mg/kg and 1.0 mg/kg were detected in optimized condtions. The recovery rate was over 87.99%. The relative standard deviation was between 3.0%-8.0%. This method is suitable for the detection of organic phosphoric pesticide due to its easy operation and high sensibility. |
