  • OXIDATION-RESISTANT COMPOSITE REVERSE OSMOSIS MEMBRANE
    Publication number: 20080203013
    Abstract: Disclosed is a oxidation resistant composite reverse osmosis membrane, comprising a porous support and a polyamide layer, in which the polyamide layer is modified by an agent so that the membrane retains a salt rejection of at least 85% after being subjected to an aqueous solution of NaClO having a concentration of about 2,000 to 30,000 ppm for about one hour. A process of preparing the membrane is also disclosed.
