Abstract
This study aimed to optimize the best conditions for the
extraction of pesticides from edible oils. In general, the
factor that had the highest impact on the pesticides’
recoveries was the solvent/sample ratio. Furthermore, each
different solvent had a different behavior when combined
with our tested cleanup sorbents. For example, acetonitrile
showed the best behavior in combination with EMR, and
some problematic analytes only conformed to our criteria
when a certain solvent/cleanup combination was used such
as deltamethrin and ethyl acetate/acetonitrile EMR-Lipid
combination. In general, the use of the ethyl
acetate/acetonitrile and Z-Sep mixture showed the highest
number of pesticides with acceptable criteria. Therefore,
each solvent/sorbent combination can be effectively used in
the multi-residue determination of pesticides from edible
oils with significant advantages in recoveries and matrix
removal over each othe
