Analytical methods for pesticide residue determination are being introduced, which are used for regulatory enforcement, risk assessment, organic food verification, trade, research and so on. For most methods, the key procedure is the cleanup of sample extracts in order to avoiding interferences from complicated matrices. In this study, multiwalled carbon nanotubes (MWCNTs) were introduced into the cleanup procedure for pesticide residues analysis in fruits, vegetable, teas, juice, meat and so on. Furthermore, a novel rapid cleanup method based on MWCNTs in a packed column filtration procedure for analysis of pesticide residues was developed, which was carried out by applying the streamlined procedure on a multiplug filtration cleanup (m-PFC) column with syringes. It is convenient and time-saving as it does not require any solvent evaporation, vortex, or centrifugation procedures. This method is expected to be widely applied for monitoring of pesticides at trace levels in the future for various agricultural commodities.
