ABSTRACT Polyimide (PI) nanofiltration (NF) membranes have garnered significant attention in water purification due to superior separation efficiency and stability. This study presents the fabrication of PI/graphene oxide (GO) NF through a non‐solvent‐induced phase inversion process, specifically for separations inorganic salts organic dyes. The chemical structures PI‐GO are characterized using Fourier transform infrared spectroscopy (FT‐IR) X‐ray photoelectron (XPS), their properties examined zeta potential measurements, contact angle tests, thermogravimetric analysis. incorporation GO significantly enhances hydrophilicity membranes, subsequently optimizing capabilities. Filtration experiments demonstrate that addition notably increases permeance PI substantially rejects negatively charged dyes such as Coomassie Brilliant Blue (CBB), Congo Red (CR), Direct Black 38 (DB38). Moreover, exhibit excellent salt ions while effectively removing Notably, also display remarkable performance with hot (50°C 90°C) CBB/Na 2 SO 4 feed solutions, indicating robust thermal These findings suggest hold substantial promise field technology, owing exceptional performance.
