▎ 摘  要

NOVELTY - Graphene oxide quantum dot functional ball nano particle comprises positively charged nanoparticles as the spherical core and support layer, where the core is wrapped by graphene oxide quantum dot. USE - The functional nano particle modified with polyamide reverse permeation membrane/nano-filter film is used for sea water and brackish water desalination, seawater and brackish water softening, and drinking water treatment and sewage treatment (claimed). ADVANTAGE - The particle modified with film can soften the water, and has multiple inlets and outlets to improve the water flux. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) functional nano particle modified with polyamide reverse permeation membrane/nano-filter film, where reverse permeation/nano filter film polyamide separation layer is inlayed with graphene oxide quantum dot function ball nanoparticle; and (2) preparing functional nano particle modified with polyamide reverse permeation membrane/nano-filter film comprising using 0.02-0.1 wt.% graphene oxide quantum dot function ball nano particle, dispersing in 0.5-3 wt.% aqueous solution of polyamine or 0.05-0.3 wt.% oil phase solution of polyacyl chloride, immersing porous base film in aqueous solution for 0.3-2 minutes, taking out, removing water and bottom film surface, soaking in oil phase solution for 0.5-2 minutes, then curing for 5-30 minutes at 45-65 degrees C, thoroughly rinsing deionized water.
