Magnetic MOFs/nanogold composite material as well as preparation method and application thereof

The invention relates to the technical field of active substance separation and enrichment, and in particular, relates to a magnetic MOFs/nanogold composite material as well as a preparation method and application thereof. The preparation method of the magnetic MOFs/nanogold composite material comprises the following steps that: a mixture of Fe3O4-MWCNT-MIL-88A, chloroauric acid, a reducing agent and water is subjected to a heating reaction. The Fe3O4-MWCNT-MIL-88A is mainly prepared by the following method: a mixed solution of fumaric acid, Fe3O4-MWCNT, a trivalent iron salt and an organic solvent is subjected to a reaction under a heating condition. The magnetic MOFs/nanogold composite material prepared by multiple steps through an in-situ polymerization method has excellent thermal stability, relatively high specific surface area and multiple micropores, and has an excellent adsorption effect on indole-3-methanol in a liquid environment. 本发明涉及活性物质分离富集技术领域，具体而言，涉及一种磁性MOFs/纳米金复合材料及其制备方法和应用。本发明的磁性MOFs/纳米金复合材料
