▎ 摘　　要

NOVELTY - Preparing graphene ion-exchange fiber comprises (i) taking raw materials (ii) performing grafting reaction using fiber carrier and the graphene to obtain the graphene fiber carrier, (iii) carrying out chloroacetal reaction for the graphene fiber carrier, crosslinking fiber macromolecule using initiator under the action of solvent, and reacting with the catalyst. USE - The method is useful for preparing graphene ion exchange fiber. ADVANTAGE - The graphene ion-exchange fiber has higher adsorption performance than the common fiber, improves the ion exchange performance, the graphene adsorption grease, ion, pigment performance, and improves the sewage treatment adsorption performance of the ion exchange fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene ion-exchange fiber prepared by the above-mentioned method.
