Abstract
Water is the source of life and one of the most precious natural resources. Nevertheless, with the fast development of industry, water containing heavy metal ions has become a global environmental threat because of their toxicity and biological accumulation. Thus, we have synthesized a facile 2D-carbon sheet, which is an inexpensive and eco-friendly adsorbent over the synthetic adsorbents. The neem leaves derived 2D-carbon was impregnated with Fe2O3 nanoparticles. The Fe2O3@2D-CS composite was characterized by using XRD, FT-IR, TEM, BET and TGA analysis. This Fe2O3@2D-CS composite was applied for the removal of Pb(II) from aqueous solution. The batch adsorption experiment data was well fitted to Langmuir isotherm model rather than Freundlich model, the adsorption capacity was reached up to 43.47 mg/g at 303 K. The adsorption kinetics study shows that the adsorption of Pb(II) ions equilibrium was achieved within 60 min following a pseudo-second-order model. The Fe2O3 nanoparticles doped 2D-CS can act as an excellent adsorbent for the removal of Pb(II) from the aqueous environment. This study illustrates that Fe2O3@2D-CS nanocomposite can be used for practical applications as a global economic material.
