Highly Chlorine‐Tolerant Polymers for Desalination

Get the salt out: Conventional polyamide desalination membranes suffer from low chlorine tolerance, leading to short membrane life. Using newly synthesized sulfonated copolymers prepared by direct copolymerization of disulfonated monomer, chlorine-tolerant desalination membranes (see picture) showing high flux and high salt rejection were developed.
