Resumo: | In this study, multiresidue method using solid phase extraction (SPE) and solid phase microextraction (SPME) are compared in the determination of pesticides in aqueous samples. Parameters such as fiber type and thickness, elution solvent, sample volume, equilibration time, partition coefficient and solubility were investigated. Satisfactory results were obtained for the analysis of pesticides using C18 cartridges and ethyl acetate as eluent, whith recovery rates between 75-107%. The best conditions for SPME fiber were PDMS with a 100 µm thick, sample volume of 40 mL, and reaction time was 45 min. SPME method is most suitable for the analysis of pesticides in water, due to its speed and simplicity and solvent-free. The limits of detection and quantification are below the maximum concentration limits established by Brazilian authorities and therefore acceptable. |
