Metal-organic frameworks (MOFs) have extremely high surface area and porosity, and their structures can be designed and regulated. However, there are some problems in its adsorption and separation in aqueous phase, such as poor water stability, poor adsorption selectivity, difficult separation from water, high cost of synthesis and regeneration. In light of this, MOFs can be functionalized purposefully to improve the adsorption performance on target pollutants. This review introduces the structural advantages of MOFs, analyzes the influencing f...
