Separation of lead ions from aqueous solutions containing 5, 10, 20, 50, 100, 200 and 500 ppm lead was studied by adsorption at the surface of talc mineral of Indian origin. The effect of temperature (20, 30, 40, 50, 60, 70oC) on adsorption phenomena was studied and the data was analyzed using Langmuir isotherm. The changes in enthalpy (H), free energy (G) and entropy (S) were evaluated. The negative values of G and H indicate the adsorption of lead ions on talc surface to be spontaneous and exothermic under the experimental conditions.
