Studying on The Removal of Pb(II) using Fire Clay -TiO2 Nanocomposite and Fire Clay


The present study was aimed at investigating the adsorption behavior of Pb(II) ions onto Fire Clay-TiO2 nanocomposite (NC) and Fire Clay (FC). The effect of several parameters such as adsorbent dose, contact time, initial concentration, pH and  temperature has been studied. The adsorption followed pseudo second order, Elkovich kinetic models. Intraparticle diffusion model has also been attempted. The adsorption of Pb(II) was found to be maximum in the pH range 7-10.5. Adsorption on both clay and nanocomposite obey Langmuir, Freundlich model. The thermodynamic parameters DG°, DH°and DS° have also been evaluated. Adsorptions on both clay and nanocomposite were found to be exothermic and chemisorptive in nature. Chromium removal was better with nanocomposite than with clay.
