NOVELTY - Preparing a slightly reduced graphene oxide nanofiltration membrane involves preparing a graphene oxide nanofiltration membrane graphene oxide dispersion through a base film to obtain a graphene oxide nanofiltration membrane. The graphene oxide nanofiltration membrane is irradiated with an ultraviolet analyzer for 0.5-36 hours to obtain the desired product. USE - Method for preparing slightly reduced graphene oxide nanofiltration membrane used on a separation membrane (all claimed). ADVANTAGE - The slightly reduced graphene oxide nanofiltration membrane prepared by the method does not require reduction of graphene oxide dispersion before film formation, and does not require additional additives such as a dispersant and a catalyst in order to avoid intercalation between the layers of graphene oxide sheets to maintain the inherent layer spacing of the graphene oxide. The method adopts ultraviolet radiation reduction, has simple operation, low energy consumption, low equipment requirement and is eco-friendly.
