| Abstract: | 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. |
