Abstract

The cost-effective, large area Carbon Nanotubes and Nanofibers (CNTs–CNFs) film was synthesized on graphite substrate by low pressure and low temperature thermal chemical vapor deposition (CVD). Successful removal ofFe3+from water by electrosorption of CNTs–CNFs films was achieved. The electrosorption capacities of CNTs–CNFs film electrodes were approximately 3.89–49.3 μmol/g at different voltages from 0.6 to 1.4 V, when the initial concentrations of ferric chloride(FeCl3)are kept around 89.1 μmol/L. The ion adsorption followed a Langmuir isotherm indicating monolayer adsorption.
