Composite polyamide membrane post-treated with nitrous acid |
| abstract |
A method for making a composite polyamide membrane comprising a porous support and a polyamide layer, including the steps of: i) applying a polar solution comprising a polyiunctional amine monomer and a non-polar solution comprising a polyiunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a polyamide layer; and ii) exposing the thin film polyamide layer to nitrous acid; wherein the method is characterized by at least one of: conducting the interfacial polymerization of step i) in the presence of a subject amine- reactive compound, or applying a subject amine-reactive compound to the interfacially polymerized polyamide layer prior to step ii), wherein the subject amine-reactive compound is different from the polyiunctional acyl halide and polyiunctional amine monomers and is represented by the following formula: |
