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　pro⁃　cess，　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　mag⁃　netic　graphene，magnetic　carbon　nanotubes，magnetic　graphitized　carbon　black　and　their　modifica⁃　tion　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　out⁃　lined．It　is　anticipated　to　provide　a　reference　for　expanding　the　application　of　mCBMs　in　the　detection　of　pesticide　residues.　©　2023,　China　Association　for　Instrumental　Analysis.　All　rights　reserved.
