Agricultural bio-waste based cellulosic materials are highly biodegradable and naturally occurring withhigh adsorption and capable of outstanding physico-chemical properties. This study elicits neotericupliftment and impending significance of graphene oxide(GO) – cellulose nanocrystal(CNC) nano-filtercomposite membrane (NFCM) for high removal of Cr3+, Co2+, Ni2+, Pb2+, Cd2+ and Methylene blue moleculesfrom industrial wastewater. We tried to direct comparison between conventional filter andNFCM composites filter and their physical and chemical properties, production costs, use and disposalin order to show the potential of Nano structural cellulose materials as a sustainable replacement forNFCM 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), FourierTransform Infrared (FTIR), Field Emission Scanning Electron Microscopy(FESEM), ThermogravimetricAnalysis(TGA) etc. The efficiency of wastewater purification of fabricated NFCM were determined byUltra Violet(UV)-vis spectrophotometer and Inductively Couple Plasma Optical Emission Spectroscopy(ICP-OES). Whereas the fabricated NFCM were highly crystalline, thermally stable, have good surfaceactivity, exhibit remarkable removal efficiency against the toxic heavy metals and soluble dye. The maximumR% was found for Cd2+ and Pb2+, around 99%. Beside this all dye molecules were removed from thewastewater simultaneously and successfully.
