l-Cysteine-Modified Graphene Oxide-Based Membrane for Chiral Selective Separation

ACS Applied Materials & Interfaces, Journal Year: 2021, Volume and Issue: 13(41), P. 49215 - 49223

Published: Oct. 9, 2021

A novel chiral separation membrane was fabricated by assembling l-cysteine (l-Cys)-modified graphene oxide sheets. l-Cys modification leads to an enantiomer with accessible interlayer spacing of 8 Å, which allows high solvent permeability. In the racemate experiments under isobaric conditions, enantiomeric excess (ee) values alanine (Ala), threonine (Thr), tyrosine (Tyr), and penicillamine (Pen) racemates in permeation solution were 43.60, 44.11, 27.43, 46.44%, respectively. negative pressure, performances Ala, Thr, Tyr still maintained, filtrate after 56.80, 54.57, 32.34%, These results indicate that as-prepared GO-Cys has a great practical value field separation.
