| Abstract: | A rapid and efficient method was developed for detecting carbamate pesticide resdues in corn flour. Residues were extracted with ethyl acetate and cleaned up with LC-Florisil SPE column, and detected with HPLC post-column direvatization system and Fluorescense Detector. The minimum Limits of determination were 0.003 2-0.004 4mg/kg, the recoveries were 82.5%-97.3%, coefficients of variation were less than 6.2%. |
