Preparation and Characterization of Graphene/Oxide Graphene Hybrid Membranes

Abstract

Graphene/graphene oxide hybrid membranes were successfully prepared by vacuum filtration and ion treatment of membranes. The structure and functional groups of membrane were characterized by SEM and FT-IR. The results show that the mixed membrane layer is more obvious and facilitates the screening of ions than untreated. A sodium ion measurement platform was set up, and a sodium ion concentration meter was used to measure the sodium ion concentration of the solution that permeated for 5 hours. The results show that the mixed membrane has a good rejection effect on sodium ion, and the rejection efficiency is about 84.08%. It will provide a basis for the future development of mixed membranes in the field of seawater desalination1
