Abstract

We present a scalable chemical method to upcycle polysulfone–graphene oxide (PSU–GO) industrial waste into customized adsorbent materials through in situ, in flow L-lysine functionalization of GO embedded in the polymer composite. Enhanced carbamazepine removal from water is demonstrated for PSU–GOLys filled cartridges.
