Adsorption of Pb(II) on Nano Sized SnO2 Derived from Sol-Gel Method

Abstract—This study investigates the applicability of SnO2 nanoparticles for the removal of Pb(II) from waste water . SnO2nano particles of 15 nm size were synthesized using a solgel method and characterized by X-ray diffraction (XRD), FTIR, SEM and transmission electron microscope (TEM). Batch experiments were carried out to study the adsorption kinetics of Pb(II) on SnO2. The effect of varying parameters such as contact time and PH on the adsorption process were examined. The adsorption process was found to be highly PH dependent. Experimental kinetic data were tested with pseudofirst –order and pseudo-second-order kinetic equations. The equilibrium data were modeled using general isotherm models. The experimental data agreed well with Langmuir isotherm model.

Index Terms—Sol–gel method, adsorption, removal of lead.
