A method for making a composite polyamide membrane including a porous support and a thin film polyamide layer, wherein the method includes: (i) applying a polar solution comprising a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer; (ii) treating the thin film polyamide layer with a polyfunctional arene compound; and (iii) exposing the thin film polyamide layer to nitrous acid; wherein the polar and non-polar solutions further comprises at least one of the following: (A) at least one of the solutions further comprises a tri-hydrocarbyl phosphate compound represented by Formula (I): and (B) the non-polar solution further comprises an acid-containing monomer comprising a C2-C20 hydrocarbon moiety substituted with at least one carboxylic acid functional group or salt thereof and at least one amine-reactive functional group.
