[Display omitted] •Fe3O4@CFR@GO was tested for the elimination of pigments in pesticide analysis.•Fe3O4@CFR@GO showed an excellent clean-up efficiency.•Satisfactory purification and recovery effects were achieved in chillimatrices. The presence of pesticide residues in food and vegetables is a growing concern forconsumers. In order to monitor these residues reliably, a selective and sensitive, multi-residue system has been developed and validated in green chilli by gas chromatography-tandem mass spectrometry (GC–MS/MS). Fe3O4@CFR@GO (Fe3O4@Catechol Formaldehyde Resin@Graphene Oxide) magnetic nanocomposite is used as reversed dispersive solid phase extraction (r-DSPE) materials. Fe3O4@CFR@GO magnetic nanocomposite is synthesized, characterised by XRD, FTIR and SEM. Comparative investigations have shown that Fe3O4@CFR@GO magnetic nanocomposite not only has high pigment removal efficiency, but also has more clean-up than typical graphitizedcarbon black(GCB). The processing of two multiple reaction monitoring (MRM) transformations for each analyte is done by GC–MS/MS in electron impact (EI) mode. Precision and accuracy were tested by recovery studies. The technique proved to bereliable and sensitive in green chilli samples for the routine testing of 35 pesticides.
