This invention belongs to the field of water treatment technology, specifically relating to a trithiocyanate-coupled graphene oxide composite material, its preparation method, and its application. To more efficiently and selectively separate and enrich copper ions in wastewater, this invention provides a trithiocyanate-coupled graphene oxide composite material, obtained by covalently coupling trithiocyanate and graphene oxide through a nucleophilic substitution reaction. This composite material exhibits excellent adsorption and removal efficiency for copper ions in complex aqueous systems with both single and multiple components, while showing minimal adsorption of other metal ions such as gallium, silver, indium, cobalt, and neodymium. Furthermore, after multiple adsorption-desorption cycle tests, the composite material maintains a high metal ion removal rate, demonstrating excellent structural stability and regeneration performance. Therefore, this composite material holds promise for the selective separation and enrichment of copper ions in complex aquatic environments, possessing excellent prospects for industrial application.
