Abstract
Adsorption of Cu (II) metal ions onto Punica granatum L. husk was studied by batch adsorption experiments. In order to get conditions for maximum adsorption studies were carried out for different initial concentrations of metal (C0), doses of the adsorbent (m), pH of solution, contact time(t) and temperature (T). Maximum adsorption was observed for 3 mg/L of initial concentration metal at pH=6 for 0.3 g adsorbent dose, 150 min contact time and 323.15 K. Thermodynamic functions such as free energy change (G0), entropy change (DS0) and enthalpy change (DH0) were estimated. Adsorption was found to be thermodynamically endothermic.
