The invention discloses a metal organic framework material as well as a preparation method and application thereof, and relates to the technical field of preparation of materials. The preparation method of the metal organic framework material comprises the following step: performing reaction on a magnetic graphene oxide/aminocyclodextrin composite material formed by compounding a magnetic graphene oxide material with aminocyclodextrin, an organic ligand and a metal compound. The method is simple in preparation process, high in controllability, low in cost and favorable for large-scale production. The metal organic framework material is prepared by the method. The material is high in stability, high in acid and base resistance, resistant to matrix interference, easy to store, high in adsorption flux and low in economical cost and can realize quick enrichment and removal of pesticide pollutants.
