Nanocellulose scaffold in the form of microfibrillated cellulose obtained from phosphoric acid hydrolysis and carboxycellulose nanofibers prepared using nitro-oxidation method have been utilized to remove the various contaminations such as dyes, heavy metal ions, arsenic, and fluoride impurities from water. The efficient metal binding of ZnO nanoparticles were obtained on the microfibrillated cellulose to trap the arsenic impurities at neutral pH. However, suitable charge (1.15 mmol/g) was generated on the surface of cellulose nanofibers using nitro-oxidation method to remove heavy metal ions and dyes impurities. Nanocellulose scaffold was found to be a sustainable and cost-effective way to remediate the impurities from contaminated water, as a wide range of impurities from 50-5,000 ppm can effectively remove in a short time-interval (&gt; 5 minutes), with excellent efficiency better than most of the existing adsorbents. Nanoscale scaffold was characterized using FTIR, SEM/EDS, TEM and AFM analysis.
