| Abstract: | An optimized analytical method using dispersive solid-phase extraction(Dispersive-SPE) and gas chromatography-mass spectrometery(GC-EI/MS) has been developed for the rapid determination of 53 pesticides in three eco-agricultural products in Southern Shaanxi.Prior to analysis,a sample preparation approach based on acetonitrile containing 0.1% acetic acid for extraction and dispersive-SPE method for cleanup was implemented and validated for pesticides.The extracts were determined by GC-EI/MS using heptachlor ... |
