Abstract:

      The issue of pesticide residues in food is of great concern£®The extraction and purification of food matrices by sample pretreatment techniques are necessary for the complex matrixes of food products containing many types of pesticides and very small amounts£®In the sample pretreatment process£¬sorbent materials play an important role£®In recent years£¬magnetic carbon materials£¨mCBMs£© have received much attention in the field of pesticide residue analysis in food due to their good purification effect£¬rapid separation and easy recovery£®In this paper£¬the preparation of magnetic graphene£¬magnetic carbon nanotubes£¬magnetic graphitized carbon black and their modification with functional groups£¬polymer and functional materials are introduced£®The application and the problems and future prospects of mCBMs in the detection of pesticide residues in food are outlined£®It is anticipated to provide a reference for expanding the application of mCBMs in the detection of pesticide residues.
