Résumé : |
Adsorption kinetics of Cu(II) from aqueous solution by low cost chemically modified saw dust of Morus alba was investigated. The samples were characterized by FT-IR, EDS, BET surface area and Zeta potential technique. The surfaces contain carbonyl and hydroxyl functional groups which act as a binding sites for Cu(II) ion. Adsorption kinetics of Cu(II) was tested by first order kinetics, Elovich and parabolic diffusion kinetic equations which shows that adsorption is a diffusion controlled process. The rate of adsorption was high at high adsorption temperature. Thermodynamic parameters like ΔH°, ΔS° and ΔG° were calculated from the kinetic data. |
