Abstract：A method for detecting 9 carbamate pesticides in vegetables was established by activated carbon purification combined with effective liquid chromatography．The sample was extracted with acetonitrile，purified by activated carbon，and concentrated and injected．This study determined the recovery and precision by adding standard recovery method．The accuracy and reliability of the method were also tested．The results showed that the recovery rate of 9 carbamate pesticides was 86.4%-108.1%，the relative standard deviation（RSD）was 0.5%-7.5%．This method is simple，rapid and economical，and can meet the requirement for detecting carbamate pesticides residue in vegetables．
