▎ 摘　　要

NOVELTY - Chlorine-resistant composite reverse penetrant membrane comprises a support layer, a polyamide separation layer and a protective layer which are sequentially stacked and the support layer and the protective layer contain graphene oxide. USE - The membrane is useful in water treatment (claimed). ADVANTAGE - The membrane enhances the bonding ability between the polyamide separation layer and the support layer and improves the chlorine resistance of the reverse penetrant membrane. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing chlorine-resistant composite reverse penetrant membrane comprising (a) mixing, heating, dissolving polymer, graphene oxide and solvent to obtain a film casting liquid, scraping the casting film on the non-woven fabric layer to form a polymer film, and obtaining a support layer by phase inversion, (b) contacting the support layer obtained in step (a) in sequence with an aqueous solution containing a polyamine and an epoxy curing accelerator and an organic solution containing a polyacid chloride, performing heat treatment to form a polyamide separation layer on the support layer and (c) contacting the membrane product obtained in step (b) with an aqueous solution containing glycerin, graphene oxide and an epoxy curing accelerator to form a protective layer on the polyamide separation layer, drying the excess aqueous solution to remove the chlorine-resistant composite reverse penetrant membrane; and (2) chlorine-resistant composite reverse penetrant membrane.
