| Abstract: | A new method used for the determination of 5 pesticides residues (p,p′-DDD, p,p′-DDE, o,p′-DDT, p,p′-DDT, bifenthrin) from vegetable samples coupling solid-phase microextraction using nano-SiO2 as its fibers with gas chromatography was presented. The experimental parameters, such as extraction time, extraction temperature, agitation and desorption time were controlled and optimized. And the new method was proved to be a fast and simple technique for the preconcentration of pesticides residues from vegetable samples. |
