| titleOfInvention | Composite polyamide membrane post-treated with nitrous acid |
| abstract | A method for producing a composite polyamide membrane comprising a porous support and a thin film polyamide layer, wherein a polar solution comprising a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer are applied to the surface of the porous support, said interfacial polymerization of monomers to form a thin film polyamide layer; and exposing the thin film polyamide layer to nitrous acid, characterized in that the thin film polyamide layer is treated with a halogenated benzene compound represented by the formula (a): In the above formula, X is selected from halogen; Y is selected from hydrogen, carboxylic acid, sulfonic acid; A, A', A" and A"' are independently selected from halogen, hydrogen, hydroxyl, alkoxy, ester, amino, keto-amide, and an alkyl group; provided that at least one of A, A', A" and A"' is selected from hydroxyl, amino, keto-amide, and the ortho or para position to at least one of A, A', A" and A"' The substituent in is hydrogen. |
