Preparation and Characterization of AgA Zeolite/Polysulfone Membranes

Abstract:

In present study, a few polysulfone composite membranes with the introduction of silver ion-exchange treated zeolite were prepared and evaluated by several characterization methods. Regularly-ordered zeolite particles were generally finely dispersed in the continuous PSF phase with appreciated organic-inorganic interfacial interactions as reflected by SEM and FTIR results. Gas permeation test shows that after incorporating zeolite the polysulfone membrane exhibits significantly decreased gas permeability for H₂, N₂, and CO₂ whereas they show increased permselectivity for CO₂/N₂, H₂/CO₂ and H₂/N₂ gas pairs as compared to neat polysulfone membrane.
