Isotherm Modeling Of Lead (II) Adsorption From Aqueous Solution Using Groundnut Shell As A Low-Cost Adsorbent
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 11
Abstract
Potentially toxic trace elements such as lead when present in high levels in water, food and soil post serious human health threats all over the world. Adsorption process using different natural materials is among the most effective techniques for removing many heavy metal ions from different types of water sources. In this study, an attempt has been made to investigate the efficiency of groundnut shells for removing lead from aqueous solutions using batch mode technique. The equilibrium data of Pb (II) was analyzed using one oneparameter, six two-parameter and two three-parameter adsorption isotherm models. The experimental data fitted well to two-parameter isotherm (Tempkin adsorption isotherm) in comparison to the other adsorption isotherm models analyzed. The correlation coefficient of Tempkin adsorption isotherm was found to be 0.9661 indicating that the groundnut shell could remove about 96.61 % of Pb (II) ion effectively from the aqueous solution.Fourier transform infrared (FT-IR) spectroscopic studies revealed the possible involvement of functional groups, such as hydroxyl, carboxyl, amino and carbonyl group in the biosorption process.
