Abstract
Water containing heavy metal ions from mineral, mining processing, synthetic chemical, and automobile manufacturing industries are one of the biggest water pollution. Therefore, we synthesized a facile eco-friendly 2D-carbon sheet, which is an inexpensive adsorbent over the inherently more costly synthetic adsorbents. The onion husk derived 2D-carbon was impregnated with ZrO2 nanoparticles. The ZrO2@2D-CS composite was characterized by using XRD, FT-IR, TEM, BET and TGA analysis. This ZrO2@2D-CS composite was applied for the removal of Cu(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 44.84 mg/g at 308 K. The adsorption kinetics study shows that the adsorption of Cu(II) ions equilibrium was achieved within 60 min following a pseudo-second-order model. The ZrO2 nanoparticles doped 2D-CS can act an excellent adsorbent for removal of Cu (II) from the aqueous environment. This study illustrates that ZrO2@2D-CS composite can be used for practical applications as a global economic material.
