NOVELTY - Preparation of aminophenol graphene oxide film involves (S1) obatining graphene oxide solution, (S2) dispersing the diluted graphene oxide solution in aqueous solution, adding precursor solution to obtain aminophenol formaldehyde resin and stirring, (S3) transferring the mixed and stirred solution to a filtering device and performing film extraction, and (S4) irradiating the drawn film under the simulated sunlight. USE - Preparation of aminophenol graphene oxide film for ensuring sustainable regeneration of ultra-fast water channel by sunlight irradiation. ADVANTAGE - The graphene oxide film is prepared by a simple, efficient, low-cost, easy-to-implement method under the same filtration operation. The film improves the water flux of the dye, and has a removal rate of nearly 100%. The film can repair the membrane channel even after many test cycles, so as to achieve long-term stable use effect.
