Abstract:
This paper presents the adsorption of Pb(II) and Cr(III) from aqueous solution on Celtek clay. Batch experiments were carried out as a function of the adsorbent dosage, solution pH, shaking time, and temperature. The equilibrium data of fitted well with the linear Langmuir and Freundlich models. Dubinin-Radushkevick (D-R) isotherm model was applied to describe the nature of the adsorption of the metals, and found that it occurred physically. Thermodynamic parameters, the change in Gibbs free energy change (DeltaG degrees), enthalpy (DeltaH degrees) and entropy (DeltaS degrees) were also calculated. These parameters indicated that the adsorption of Pb(II) and Cr(III) on Celtek clay was feasible, spontaneous and exothermic process in nature. Based on the results, it was concluded that Celtek clay had a significant potential for removing Pb(II) and Cr(III) from wastewater using adsorption method.
