As a result of serious pollution in the water environment, sewage disposal has been receiving lot attention from industry. Metal-organic frameworks (MOFs) attract interest adsorption and separation due to their complex structures easily adjustable pore sizes. Magnetic MOFs inheriting advantages both large surface area easy recovery have great potentials pollutants. This paper reviews recent research progress on ions, dyes other contaminants by different types (magnetic non-magnetic MOFs) magnetic composites (Fe3O4@MOF) aqueous environments. The factors affecting pollutants, thermodynamic kinetic effects are discussed with detailed examples. Finally, challenges opportunities for further development elucidated.
