▎ 摘  要

NOVELTY - The graphene oxide stripping method involves uniformly stirring a mix solution and potassium permanganate, and then cooling the mixture to room temperature. Hydrogen peroxide solution of certain quantity is added to the mixture. The resulting mixture is subjected to reducing reaction, washing and drying to obtain graphene oxide. Waste water liquid is added to and mixed with prepared graphene oxide for 3-48 hours. A preset amount of graphene oxide is stripped off the content of waste liquid to perform solid-liquid separation and obtain rear adsorption of waste water liquid of graphene oxide. USE - Graphene oxide stripping method for PCB waste treatment. ADVANTAGE - Simplifies preparation and shortens production period of PCB material without generating pollution and consuming large amount of energy.
