Abstract:Metal-organic framework (MOFs) materials are widely used in the field of sewage treatment, with the advantages of large specific surface area, ultra-high porosity, adjustable pore size, modification after synthesis and high thermal stability. However, how to separate and reuse MOFs materials in wastewater has always been the bottleneck of its practical application. Magnetic metal-organic framework (MMOFs) is a new type of magnetic adsorbent material, which is composed of MOFs material and magnetic material. It not only retains the structure and performance characteristics of MOFs material, but also adds magnetism to the composite, so it can easily separate the adsorbent from water. This article introduced the development status of MMOFs materials as adsorbents, and focuses on the preparation methods of MMOFs materials and their detection and treatment of heavy metals and organic pollutants in water. Finally, the existing problems and challenges of MMOFs materials are summarized, and the future research hotpots are reasonably prospected.
