Abstract: Graphene oxide/chitosan composite material is a new type of biodegradable material that has been newly developed in recent years. The huge specific surface area, abundant oxygen-containing functional groups and amino groups of the composite material make it a good adsorbent. This article reviews the research progress of graphene oxide/chitosan composite materials in adsorption applications in recent years, and the focus is played on the common preparation methods of the composite materials and the adsorption of metal ions and organic dyes in sewage treatment, and a brief discussion is conducted on the desorption regeneration performance of the composite material.
