Research on Application of MOFs in Adsorption Treatment of Wastewater Pollutants

Industrial wastewater not only greatly damages the ecological environment,but also seriously threatens human health.Metal organic framework materials(MOFs)are a new type of porous materials.Their ultra-high specific surface area,adjustable pore size and other advantages have played an important role in the field of selective adsorption separation.This paper introduced the research progress of MOFs in the adsorption and removal of various pollutants in wastewater,such as heavy metal ions(Hg²⁺、U⁶⁺、Cr⁶⁺、Cd²⁺、Pb²⁺、Co²⁺、Sb⁵⁺、Sr²⁺)and metalloid ions(As³⁺、As⁵⁺),organic pollution substances(dye molecules,aromatic compounds),etc.,the adsorption performance of MOFs and modified MOFs materials on pollutants in wastewater was discussed.The application prospects of MOFs materials in wastewater pollutant adsorption and treatment was proposed.MOFs with low cost,highly stability and catalytic properties are ideal materials for wastewater adsorption and treatment.
