Abstract

Abstract : The kinetics, thermodynamics, and isotherms during electrical removal of Cu 2+ by carbon nanotube and carbon nanofiber (CNT-CNF) electrodes in CuCl2 solution were studied under different solution temperatures, initial Cu 2+ concentrations, and applied voltages. The result shows that Langmuir isotherm can describe experimental data well, indicating monolayer adsorption, and higher Cu 2+ removal and rate constant are achieved at higher voltage, lower initial Cu 2+ concentration, and higher solution temperature. Meanwhile, the thermodynamics analyses indicate that the electrical removal of Cu 2+ onto CNT-CNF electrodes is mainly driven by a physisorption process.
