%X Supercritical fluid extraction(SFE) of pesticide residues of chlorothalonil, aldrin, dieldrin, and endrin from chives was evaluated. A mixture of vegetable sample: anhydrous magnesium sulfate(2:3) was used for extraction. The extract was analyzed by GC/ECD. The optimum SFE conditions for the pesticides in spiked samples were studied by orthogonal experiment. The chosen conditions were 30.40 MPa, 40 degrees C, 1 min static time, dynamic extraction with 15 mL of CO2, and collection in 3 mL of ethyl acetate. All the pesticides were extracted satisfactorily from their matrix.
