Objective A new method for the separation and enrichment of pyrethroid pesticides in vegetables was developed by combining QuEChERS with disposable polyethylene pipet assisted dispersed liquid-liquid micro-extraction （DPP-DLLME）.Methods Firstly， acetonitrile was used as extraction agent for separation of pyrethroid pesticides from vegetable samples， and the collected acetonitrile extract was purified， then used as the dispersant of DPP-DLLME. A disposable dropper was used as the extraction vessel for DPP-DLLME， and n-octanol was used as the extractant. After phase separation， the extractant was floating on the aqueous solution and concentrated in the narrow neck of the pipet， which can be directly withdrawn by a microsyringe for instrument analysis.Results Under the optimized extraction conditions， the linearity range was 0.5-200 ng/g with correlation coefficient r² higher than 0.995 for seven pyrethroid pesticides. The limits of detection were in the range of 0.04-0.1 ng/g， and the limits of quantitation were in the range of 0.1-0.5 ng/g. The recoveries at three spiking levels of 1， 10 and 100 ng/g were in the range of 94.5%-110.5% with the RSDs less than 9.0% （intra-day） and 8.2% （inter-day）.Conclusion The method was simple and effective， which provided a new choice for the detection of pyrethroid pesticides in vegetables.
