摘要:

制备了锆1,4⁃羧基苯(UiO⁃66)系列金属有机骨架(MOF)材料,对比了不同MOF材料对重金属离子的吸附性能,并制备了聚醚砜/聚醚酰亚胺/改性MOF(PES/PEI/MOF)复合膜,对比了MOF添加量对膜重金属离子吸附和渗透性能的影响。结果表明,在UiO⁃66系列MOF材料中,UiO⁃66⁃NH2对重金属离子的吸附性能最好;在其负载量为15 %(质量分数,下同)时,复合膜对重金属离子的截留性能最好。

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
