New sorbents for extraction and microextraction techniques [PDF]

open access: yesJournal of Chromatography A, 2010
This review outlines recent progress in the research on some new classes of sorbents for extraction and microextraction techniques. Carbon nanotubes are allotropes of carbon with cylindrical structure. They are very stable systems having considerable chemical inertness due to the strong covalent bonds of the carbon atoms on the nanotube surface.
