摘要

A method is described for the analysis of aldicarb and its metabolites in urine by GC/FPD. The sample was concentrated with activated charcoal-Florisil column chromatography, eluted by dichloromethane-acetone (1:1v/v). The aldicarb, aldicarb sulfoxide in the eluted solution were oxidized by oxidizing reagent into aldicarb sulfone. The concentration of aldicarb sulfone was analyzed by GC/FPD. The detection limit of 0.0024 mg/L and coefficient of variation of 2.4%-7.4% were achieved. Mean recovery rates were 90.9%, 86.6%, 92.6% for aldicarb, aldicarb sulfoxide and aldicarb sulfone, respectively.
