Microporous membranes for ultrafast and energy-efficient removal of antibiotics through polyphenol-mediated nanointerfaces

Yu Wang et al.

Summary: The overuse and misuse of antibiotics pose significant risks to human health, necessitating breakthrough technologies to eliminate antibiotics from water. This study explores the use of polyphenol-based nanoengineering to functionalize conventional microporous membranes, enabling ultrafast removal of multiple antibiotics in a flowthrough purification system.

Cardopoly(arylene ether sulfone)s membranes bearing N-cyclic cationic groups enable high performance during both diffusion dialysis and electrodialysis

Wenke Xia et al.

Summary: In this study, a series of cardopoly(arylene ether sulfone) membranes with different physicochemical structures were prepared. These membranes exhibited high permselectivities during diffusive dialysis (DD) and electrodialysis (ED) processes. The high permselectivities were attributed to the rigid and contorted structures containing cardo groups and pendant N-cyclic QA cations, enabling the formation of unique nano ion channels. Microphase separation and the distance between the AEMs and CEMs were found to influence the ED performance of the membranes. The results suggest new designs for high-performance ED and DD membranes.
