Magnetic MOF materials,as a new type of multifunctional material,have attracted widespread attention in the field of water treatment.Based on the unique physicochemical properties of MOF materials (such as porous structure,high specific surface area,unsaturated metal sites,etc.),grafting them with magnetic materials (such as Fe3O4,iron,nickel,etc.) results in magnetic MOF materials with high activity,adsorption sites,and magnetic properties,and they can be widely applied in catalysis,adsorption,separation,and other fields to achieve efficient adsorption and removal of pollutants.This paper provided a detailed review of the synthesis and graft modification of magnetic MOF materials,and summarized their applications in water treatment,such as dye wastewater and heavy metals,as well as their regeneration.In addition,it also provided a prospective outlook on more effective regeneration methods and the adsorption and degradation mechanisms of various new pollutants such as microplastics.
