Abstract

Abstract:

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 adsorption 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.

Key words: zirconium 1， 4?carboxybenzene, composite membrane, heavy metal ion, adsorption property
