Investigation of factors affecting adsorption of transition metals on oxidized carbon nanotubes
Z Gao, TJ Bandosz, Z Zhao, M Han, J Qiu - Journal of Hazardous Materials, 2009 - Elsevier
Adsorption of nickel, copper, zinc and cadmium from aqueous solutions on carbon
nanotubes oxidized with concentrated nitric acid was carried out in single, binary, ternary
and quaternary systems. TEM and adsorption of nitrogen were used to determine texture
and structural parameters, respectively. The surface chemistry was evaluated using the pH
at the point of zero charge, FTIR spectroscopy and XPS analysis. The experimental results
showed that all isotherms for Cu2+ (aq) fit to Langmuir model in each system. On the other …
