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.


Es wurde die Adsorptionskinetik von Cu(II) aus wässriger Lösung an preiswertem, chemisch modifiziertem Sägemehl des Morus alba untersucht. Die Proben wurden mit Hilfe der FT-IR, EDS, BET-Oberfläche und der Zeta-Potentialtechnik charakterisiert. Die Oberflächen enthalten funktionelle Carbonyl- und Hydroxylgruppen, die Bindungsplätze für die Cu(II)-Ionen darstellen. Die Adsorptionskinetik wurde mit dem Erster-Ordnung- und dem Elovich-Modell sowie mit der parabolischen Diffusionsgleichung, die zeigt, dass die Adsorption ein diffusionskontrollierter Prozess ist, geprüft. Die Adsorptionsgeschwindigkeit was hoch bei hohen Temperaturen. Aus den kinetischen Daten wurden thermodynamische Größen wie ΔH°, ΔS° und ΔG° berechnet.
