Resumen:
This paper presents a review of the environmental possibilities of using carbon nanotubes
(CNTs) for extracting metals, taken into account the characteristics of carbon nanotubes to be used
as adsorbents and the influence of different factors on the adsorption processes, among them: kind
of carbon nanotubes used as adsorbent, particle size, pH of solutions and diameter and length of
carbon nanotubes. Also, some images of transmission electron microscopy (TEM), atomic force
microscopy (AFM) and molecular modeling (Materials Studio Software) obtained by our research
group are presented.
