Abstract:
A method for making a composite polyamide membrane comprising a porous support and a thin film polyamide layer, wherein the method comprises the step of applying a polar solution including a polyfunctional amine monomer and non-polar solution including a polyfunctional acyl halide monomer to a surface of the porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the method is characterized by the step of applying a non-polar solution comprising an aliphatic acyclic tertiary amine compound to the support.
