a Volumetric charge density and volumetric density. b O/N ratio and NH–C = O content from N1s, which was characterized by X-ray photoelectron spectroscopy (XPS). c Pore distribution that was calculated from the neutral molecule transport method. d Single salt rejection and salt/water flux of the A-PA and SAD polyamide membranes. The error bars represent the reproducible data obtained from at least three independent membrane samples.
