Research progress on the removal performances and mechanisms of MOF membranes for metal ions
Metal organic frameworks(MOFs),which have the characteristics of high permeability,high selectivity,adjustable pore size and topological structure,have shown great advantages in the adsorption and reduction of metal ions.Therefore,they are widely used in the synthesis of MOF membranes.In this paper,the synthesis methods of MOF membranes and the abilities of MOF membranes to remove metal ions are reviewed.The influencing factors of MOF capacity,temperature,pH,membrane flux and membrane pore size on the removal performances of metal ions by MOF membranes are emphatically discussed.On this basis,the adsorption and filtration mechanisms of MOF membranes on metal ions are summarized,and the application prospects of MOF membranes in metal ion removal are prospected.It is hoped to provide reference for the engineering application of MOF membrane.
