    Agricultural bio-waste based cellulosic materials are highly biodegradable and naturally occurring with high adsorption and capable of outstanding physico-chemical properties. This study elicits neoteric upliftment and impending significance of graphene oxide(GO) – cellulose nanocrystal(CNC) nano-filter composite membrane (NFCM) for high removal of Cr3+, Co2+, Ni2+, Pb2+, Cd2+ and Methylene blue molecules from industrial wastewater. We tried to direct comparison between conventional filter and NFCM composites filter and their physical and chemical properties, production costs, use and disposal in order to show the potential of Nano structural cellulose materials as a sustainable replacement for NFCM filter for removal of heavy metals and dyes from industrial wastewater treatment technologies. The prepared GO, CNC, and NFCM were characterized by using X-ray Diffraction(XRD), Fourier Transform Infrared (FTIR), Field Emission Scanning Electron Microscopy(FESEM), Thermogravimetric Analysis(TGA) etc. The efficiency of wastewater purification of fabricated NFCM were determined by Ultra Violet(UV)-vis spectrophotometer and Inductively Couple Plasma Optical Emission Spectroscopy(ICP-OES). Whereas the fabricated NFCM were highly crystalline, thermally stable, have good surface activity, exhibit remarkable removal efficiency against the toxic heavy metals and soluble dye. The maximum R% was found for Cd2+ and Pb2+, around 99%. Beside this all dye molecules were removed from the wastewater simultaneously and successfully. © 2023 The Korean Society of Industrial and Engineering Chemistry
