In this study, a novel functional material was prepared by
molecular imprinting technique using a room temperature ionic liquid-
mediated template that avoided the drawback of traditional
preparation methodologies. The prepared material showed improved
stability, good selectivity and high adsorption capacity for
dichlorvos, and was more suitable as sorbent for SPE than the
C18. Thus, a sensitive and fast method for the determination of
trace dichlorvos was successfully developed. This method was
evaluated for the analysis of cucumber and lettuce samples spiked
with low levels of dichlorvos and good recoveries were achieved.
The results of this study demonstrated that this MISPE–HPLC
method will be a valuable and affordable tool for the monitoring
of dichlorvos residues in foods
