| dc.description.abstract | This research studied isotherm and thermodynamic adsorption of Pb(II) on sulfuric acid activated Cengar clay. Cengar clay was activated by various moles of sulfuric acid (0.2, 0.4 and 0.6 mol). The adsorption process of Pb(II) on the sulfuric acid activated Cengar clay was observed under batch system at various of Pb(II) concentration and temperature for 90 minutes. The observed data was analyzed with isotherm and thermodynamic. The research results showed the adsorption model of Pb(II) on all of the sulfuric acid activated Cengar clay accordance with Freundlich isotherm. Furthermore, adsorption process of Pb(II) on the Cengar clay activated by 0.2 moles of sulfuric acid occurs with endothermic, where ∆H 29,672 kJ/mol, ∆S 116,063 J/molK and ∆G - 5,784 kJ/mol, respectively. | en_US |
