The suppression of membrane fouling has been a severe challenge faced by membrane industry. In this study, zwitterionic amino acid l -cysteine were grafted on to the commercial thin-film composite (TFC) aromatic polyamide reverse osmosis membranes in order to improve membrane fouling resistance. The modification was carried out through bonding the thiol group of the l …
