NOVELTY - Graphene reverse osmosis composite membrane, prepared by (i) pouring graphite oxide and silver nitrate aqueous solution into stirring device and mixing and stirring to obtain pre-coating; (ii) pouring the obtained paint into a centrifuge for centrifugal washing, removing the foam and floating matter in the pre-paint, and obtaining the secondary processing paint; (iii) pouring the obtained secondary processing paint into the stirring device again, and adding an organic solvent in the stirring device to mix to obtain the final paint; (iv) applying the coating to the surface of the base membrane by electrospinning to obtain a semi-finished reverse osmosis composite membrane; and (v) adding semi-finished reverse osmosis composite membrane into a washing tank, adding alkaline solution, and washing. USE - Used as graphene reverse osmosis composite membrane. ADVANTAGE - Graphene material is added in the preparation process, and the strong adsorption capacity of graphene can be used to effectively filter out sediment, heavy metals, and chemical residues, and at the same time, it can effectively purify microorganisms and bacteria, which in turn improves the filtration effect, and solves the problem that the traditional reverse osmosis composite membrane has a single filtration function and poor filtration effect due to the filtration and purification of physical properties.
