While the detrimental effect of concentration polarization (CP) on water flux and solute rejection in pressure-driven membrane processes has been extensively explored, impact CP selectivity between solutes these somewhat overlooked. Considering growing interest solute–solute selectivity, this study, we explored ion–ion nanofiltration (NF) membranes. We first show discuss "reversed" observed trend monovalent cations NF, which is opposite to ions' hydrated size mobility solution. Next, apply film theory using three independent approaches evaluate extent boundary layer adjacent surface, from real ions can be calculated. Our calculated rejections cations, were higher correspondence with hydration properties solution, suggest that played a major role observed. Last, demonstrate how adversely affects commonly pursued monovalent–divalent ion separation NF. Overall, our results highlight necessity rigorously account for future studies NF minimizing as primary step improve solutes.

The efficient removal of organic contaminants from high-salinity wastewater is crucial for resource recovery and achieving zero discharge. Nanofiltration (NF) membranes are effective in separating compounds monovalent salts, but they typically exhibit an excessive rejection divalent salts. Modifying the charge characteristics NF can improve salt permeation; however, role spatial distribution governing transport behavior not fully understood. In this study, we developed a mix-charged membrane with horizontal by employing interfacial polymerization combined polyester template etching solvent-induced polyamine intercalation strategy. ratio positive to negative domains be precisely controlled adjusting aqueous monomer modifier type. X-ray photoelectron spectroscopy (XPS) depth profiling separation layer thickness analysis confirmed complete penetration polyamines into layer, providing direct evidence formation horizontally distributed domains. This unique results high density near-electroneutral surface, which facilitates permeation size-dependent "plug-in" modification covalent cross-linking further reduce pore size, enhancing small molecules. Additionally, demonstrated exceptional antifouling performance against both negatively positively charged pollutants, attributed its smooth surface. Molecular dynamics (MD) simulations revealed that weak electrostatic interactions tightly bound hydration contribute membrane's superior properties. work provides valuable insights design tailored microstructures distributions improved water treatment performance.
