  • Abstract

    Systematic batch mode studies on adsorption of Pb(II) onto Stishovite clay were carried out as a function of parameters like initial metal concentration, contact time, pH and temperature. The Langmuir and Freundlich adsorption models were applied and the equilibrium data fitted well with both isotherms. The pseudo-second-order kinetic, Elovich, intraparticle diffusion models were tested for the kinetic study. The final results showed that the adsorption process under study could be best described by the pseudo second order equation. Intra particle diffusion studies showed mainly boundary layer effect. Thermodynamic parameters revealed that the adsorption to be spontaneous and endothermic
