NOVELTY - Preparing vortex graphene oxide membrane involves preparing a certain concentration of oxidized water suspension graphene for 30-30 hours, until the solution is uniformly dispersed, and taking out. The mechanical stirring apparatus is refitted, the drill bit is used to replace the blade stirring paddle, building mechanical stirring and floxacin filtering device, the mechanical stirring is opened, add a certain volume of dispersed graphene oxide solution, add into the floxicin funnel, mechanically stir, filter and forming film on the polyvinylidene fluoride micro-porous film substrate, and taking off the film, drying, and preparing vortex-graphene oxide membrane. USE - Method for preparing vortex oxidation water graphene purifying film used in seawater desalination, sewage treatment, ion separation and nanofiltration separation and analysis field. ADVANTAGE - The device is simple, green without pollution, does not need complex reaction process and rigorous reaction condition, low cost, has large scale application potential, and has very wide application prospect in the water purifying direction.
