Electrospun Adsorptive Nanofibrous Membranes from Ion Exchange Polymers to Snare Textile Dyes from Wastewater (Adv. Mater. Technol. 10/2021)

Abstract

Increasing discharges of industrial wastewater, along with ever-stricter regulations for the candidates for the treatment of dye-laden wastewater. Owing to their facile syntheses and unique properties, these membranes show promising potential in environmental applications.Received: ((will be filled in by the editorial staff))Revised: ((will be filled in by the editorial staff))

Solution Viscosity‐Mediated Structural Control of Nanofibrous Sponge for RNA Separation and Purification

“…Most recently, 3D monolithic nanofibrous materials have attracted significant research attention due to their high porosity, highly interconnected pore structure, high integrity, as well as high‐density active sites, [ 16 ] which renders the nanofibrous aerogels a promising candidate for high rapid adsorption and separation of targeted molecules. [ 17–19 ] Recently, a carboxylated inorganic nanofibrous aerogel with hierarchical cellular structure was engineered by freeze‐drying method and employed as ion‐exchange chromatography media for the separation of proteins with much higher adsorption capacities and faster separation rates of lysozymes than bead fillers and carboxylated nanofibrous membranes. [ 20,21 ] In fact, the ameliorated chromatographic performance could be attributed to the combination of nanofibers and functional polymers in the mixed slurry for freeze‐drying.…”
