英文摘要: Abstract(#br)Draw solute is a key element of forward osmosis (FO) technology. Here we design a cage-like supramolecular material of N-(hexamethylenetetramine) propane-1-sulfonate (HMTA + − SO 3 − ) for the simultaneous wastewater remediation and protein enrichment via FO processes. HMTA + − SO 3 − reclaims water efficiently with a transfer rate of 36.0 LMH at 1.0 M without reverse solute diffusion, outperforming the conventional NaCl draw solute that produces a smaller water flux coupled with severe solute leakage. The good performance originates from the innate nature of HMTA + − SO 3 − that can create a sufficiently high osmotic pressure to drive the FO process and form a supramolecular network with H 2 O via hydrogen-bonding to prevent solute leakage. Protein enriched by HMTA + − SO 3...
