-
Samples were treated via solid-phase micro-extraction(SPME) and analyzed by HPLC equipped with a fluorescence detector to detect carbamate pesticide residues in vegetables.The effects of fiber coatings on the extracting efficiency,factors influencing the extraction process and treatment for the vegetables were investigated.LOD of the method for different pesticides ranged from 0.4×10-9 to 40×10-9 g/g.Linear range was from 0.05 to 1 mg/L.The recovery rate was from 74.4% to 108.4%.RSD was from 4.26% to 13.97%.
