Conteúdo: |
A method of extraction based on matrix solid-phase dispersion has been developed, optimized, and validated by chromatographic analysis of cypermethrin pesticide residues in samples of cows? milk. Milk (0.25 g) was fortified with cypermethrin and blended with 1 g each of C18 (octadecylsilane) silica and Na2SO4 (anhydrous sodium sulfate), used to trap fats and water, respectively. The homogenized material was transferred to a commercial SPE cartridge containing 1 g activated Florisil with 5 mL acetonitrile. Cypermethrin was eluted under vacuum with 5 × 2 mL acetonitrile and the extract was concentrated to 1 mL and analyzed by gas chromatography?mass spectrometry. The limits of detection and quantification of the method were 0.025 and 0.08 mg kg?1, respectively. |
