abstract = "Lead (Pb) toxicity in drinking water has become a serious problem worldwide particularly in the developing nations, which leads to promotion of various Pb removal methods from polluted water. Carboxycellulose nanofibers (CNF) were prepared from raw jute fibers using a one-step nitro-oxidation approach based on nitric acid/sodium nitrite. The main characteristics of extracted CNF with low crystallinity (\textasciitilde{} 35\%), good carboxylate content (1.15 mmol/g), and highly negative surface charge (− 70 mV) made them an suitable nanomaterial for removal of Pb(II) ion from water. In the experimental results, we find that 0.2 wt\% concentration of CNF suspension is capable to remove a wide range of Pb(II) ions from 50 to 5000 ppm in a very short time, where the adsorption proficiency of CNF was found to be around 2200 mg/g based on Langmuir isotherm. The high removal efficiency of CNF was due to the combined effects of adsorption and mineralization of lead crystals. Finally, nanoscale lead crystallizations on nanocellulose scaffold further inveterate by FTIR, UV–visible spectroscopy, SEM-EDS, and TEM analysis.",
