Abstract:
1. A method for treating carbon nanotubes, comprising: dispersing said carbon nanotubes in a dispersing medium to prepare a dispersion system; mixing said dispersion system with an adsorbent so that type-specific carbon nanotubes contained in said dispersion system are absorbed onto the adsorbent, wherein the adsorbent is modified by a chemical/biological modifier so as to have different adsorption selectivity to carbon nanotubes of different types; and separating the adsorbent from the dispersion system, whereby the type-specific carbon nanotubes adsorbed onto the adsorbent is separated from the carbon nanotubes of another type enriched in the dispersion system.
