NOVELTY - A flux-controllable carboxylated graphene oxide nanofiltration membrane is prepared by adding meta-xylylenediamine to carboxylated graphene oxide solution, ultrasonicating, applying to polyether sulfone base-membrane surface via vacuum self-assembling method, washing with deionized water, soaking in trimesoyl chloride/hexane solution, reacting, washing with hexane solution, and drying. USE - Method for preparing flux-controllable carboxylated graphene oxide nanofiltration membrane.
