- •
Modified QuEChERS method was used to extract 171 pesticides in cowpea samples.
- •
MWCNTs was used to clean up the cowpea matrices containing a lot of pigments.
- •
The clean-up effect of MWCNTs was obviously superior to GCB and PSA.
- •
The method was successfully applied to monitor pesticide residues in cowpea samples.
