Abstract
Temperature effects on adsorption of Pb (II) and Cd (II) onto Punica granatum L. husk for optimized predetermined conditions has been studied by batch adsorption experiment for different contact time between adsorbate and adsorbent. The adsorption was found to increase with rise in temperature. Thermodynamic functions like equilibrium constant (K), free energy (∆G 0 ), entropy (∆S 0 ) and enthalpy (∆H 0 ) for adsorption were estimated. The adsorption process was found to be endothermic with increase of randomness at solid-liquid interface.
