| Abstract: | An accurate SPE-GC/MS method for the determination of Carbofuran and 3-Hydroxycarbofuran in vegetables was developed.Vegetable samples were extracted with acetonitrile,and then clean-up was carried out by MAGA BE carbon/NH2 SPE cartridge.Precision and accuracy were assessed by adding Carbofuran and 3-Hydroxycarbofuran into vegetables at four concentration levels between 0.16 and 1.00 mg/kg using six replicates at each level.The average recoveries of Carbofuran were 94.3 %,99.1 % and 97.7 % with the RSD betw... |
