Porous Anion Exchange Membrane for Effective Acid Recovery by Diffusion Dialysis

Abstract: Diffusion dialysis (DD) employing anion exchange membranes (AEMs) presents an attractive opportunity for acid recovery from acidic wastewater. However, challenges exist to make highly acid permeable AEMs due to their low acid dialysis coefficient (Uacid). Here, a series of porous and highly acid permeable AEMs fabricated based on chloromethyl polyethersulfone (CMPES) porous membrane substrate with crosslinking and quaternization treatments is reported. Such porous AEMs show high Uacid because of the large free… Show more

“…Ion-exchanged resins are present in the anion-exchange membrane (AEM) of the filter. They bind, sequestrate, and then remove target compounds from blood during dialysis treatment [ 4 , 5 , 6 ]. This kind of resin has ionizable groups that dissociate and undergo an ion exchange with the external solution, especially in an aqueous environment [ 7 ].…”
