Regulatable pervaporation performance of Zn-MOFs/polydimethylsiloxane mixed matrix pervaporation membranes
文献摘要:
Pervaporation(PV)is an emerging separation technique for liquid mixture.Mixed matrix membranes(MMMs)often demonstrate trade-off relationship between separation factor and flux.In this study,by changing the organic linkers(2-methyl imidazolate,imidazole-2-carboxaldehyde,2-ethyl imidazolate),ZIF-8,ZIF-90 and MAF-6 were prepared and filled in polydimethylsiloxane(PDMS)membranes for deal-coholization of 5%(mass)n-butanol solution,and the membranes properties and pervaporation perfor-mances were adjusted.Compared with the pure PDMS membrane,the addition of ZIF-8 resulted in a 9%increase in flux(1136 g·m-2·h-1)and a 22.5%increase in separation factor(28.3),displaying anti-trade-off effect.For the MAF-6/PDMS MMMs(2.0%mass loading),the pervaporation separation index(PSI)and separation factor were 32347 g·m-2·h-1 and 58.6 respectively(increased by 34%and 154%in contrast with that of the pure PDMS membrane),and the corresponding permeation flux was 552 g·m-2·h-1,presenting great potential in the removal butanol from water.It was deduced that the large aperture size combined with moderate hydrophobicity of metal-organic frameworks(MOFs)favor the concurrent increase in permeability and selectivity.
