▎ 摘　　要

NOVELTY - A water treatment membrane comprises an interfacially formed polyamide layer residing upon a microporous support film, and graphene oxide quantum dots (1) attached to an outer surface of the polyamide layer, where the polyamide layer has a permeate flux and a salt rejection performance, and the permeate flux is increased by the graphene oxide quantum dots attached to the outer surface of the polyamide. USE - Membrane such as reverse osmosis membrane used for treating feed water (claimed). ADVANTAGE - Water treatment membrane has excellent quality, water flux, fouling resistance, chemical resistance, and salt rejection characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) Manufacture of the water treatment membrane, which involves impregnating a microporous plastic support film (5) with an aqueous solution of a polyamine, contacting the aqueous solution with a hydrocarbon solution of a polyacyl halide, forming a polyamide discriminating layer on the surface of the microporous support film, and contacting the polyamide discriminating layer with a solution of a graphene oxide quantum dots such that the graphene oxide quantum dots attaches to an outer surface of the polyamide discriminating layer, where the water treatment membrane is generated facilitating an increase in membrane flux, and (2) Treatment of feed water with a nanofiltration membrane, which involves coating nanofiltration membrane comprising graphene oxide quantum dots. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-section of a portion of a composite membrane.
