ADVANTAGE - The acid chlorinated graphene oxide modified polyamide reverse osmosis membrane has water flux rate, and high salt rejection rate. DETAILED DESCRIPTION - Preparing acid chlorinated graphene oxide modified polyamide reverse osmosis membrane with antibacterial property comprises (i) dissolving polyfunctional aromatic amine compound in water, to obtain 0.1-10 wt.% aqueous solution, soaking support layer in aqueous solution, removing excess aqueous solution on surface of support layer; (ii) soaking the step (i) product in 0.02-2 wt.% oil phase solution, adding polyfunctional acid chloride solution in organic solvent, removing excess oil phase solution from the surface, evaporating oil phase solution, to obtain unmodified reverse osmosis membrane; (iii) uniformly mixing 0.1-5 g/l graphene and 0.1-1 g/l thionyl chloride solution in isoparaffin solvent in a pressure of -0.1 to -0.03 Mpa, carrying out rotary evaporation of thionyl chloride at 50-80 degrees C, to obtain acid chlorinated graphene oxide modifier, uniformly coating acid chlorinated graphene oxide modifier on step (ii) obtained reverse osmosis membrane, allowing to stand for 120-1200 seconds, removing the excess modifier, where the graphene is monolayer; and (iv) drying step (iii) obtained reverse osmosis membrane at 60-100 degrees C for 80-600 seconds, to obtain the final product.
