| Zusammenfassung: | Carbon nanotubes and nanofibres (CNTs-CNFs) films have been grown on Ni sheets by low pressure chemical vapor deposition system and show good physical adsorption capability for ferric (Fe(3 + )) ions. The studies of adsorption kinetics and isotherms indicate that Fe(3 + ) adsorption process was regarded as first-order model and followed a Langmuir isotherm indicating monolayer adsorption. The saturated CNTs-CNFs film is easy to be regenerated by electrodesorption with direct voltage applied. The result shows that the combination of adsorption and electrodesorption by CNTs-CNFs is a promising technology to remove the Fe(3 + ) contamination in solution, which can be further extended to the process of other heavy metal ions |
