Fabrication of PES/modified UiO-66 composite membrane for separation of heavy metal ions
A series of metal organic framework(MOF)materials based on zirconium 1,4-carboxybenzene(UiO-66)were prepared,and their adsorption properties for heavy metal ions were comparatively investigated.The poly(ether sulfone)/poly(ether imide)/modified MOF composite membranes were then prepared,and the effect of MOF content on the ad-sorption and permeability of heavy metal ions was compared for the as-prepared membranes.The results indicated that UiO-66-NH2 exhibited the best adsorption performance for heavy metal ions among the prepared MOF materials,and its retention performance for heavy metal ions was optimal at a loading of 15 wt%in the composite membranes.
