Abstract：Pesticide residues in vegetables can cause serious impact on human health,so its rapid detection technology has important practical significance.Tthe phosphate buffer solution and methanol solution were used for surface of vegetable pesticide residues rinse extraction process.The extraction effect and influencing factors of the two technologies on different pesticide residues of the different vegetables were analyzed.A kind of micro organization comminuter fast dolly extraction method was proposed in this research.The result showed than the efficiency of pesticide residues extracted was improved over 70％ through the fast dolly extraction method.In conclusion,the residence time played an important role in the pesticides in vegetables surface extraction efficiency,and the fast dolly extraction method could effectively improve the efficiency of pesticide residues extracted and detection accuracy.
