Adsorption kinetics of copper (II) using bioadsorbents
Keywords:
Bioadsorbents, Saltbush, Taioba-BravaAbstract
Dehydrated leaves of Saltbush (Atriplex Nummularia Lindl) and Taro (Colocasia Antiquorum Schott), popularly known in Brazil as Taioba-Brava, were used as bioadsorbents in the Cu2+ removal from aqueous solutions in order to verify the maximum adsorption capacity (qe) as well as the kinetic parameters. According to the results obtained by atomic absorption spectroscopy (AAS), in the quantification of Cu2+ adsorbed by the bioadsorbents, it was possible to evaluate the percentage removal of these ions. The experimental data were found to fit quite well with the pseudo-second order kinetic models indicating that the Saltbush bioadsorbent presented a higher adsorption capacity than the Taioba-Brava one. Furthermore, the rate constants, at 27 ºC, were also determined.Downloads
