    摘要: A novel microwave-assisted process is described for the rapid removal of catalytic metal and non-desirable carbon impurities in fullerene, single wall, and multiple wall carbon nanotube preparations. The purification process is carried out at various programmed pressures, power levels and reaction times in a suspension of the nanocarbon moieties in the presence of strong acids (for example, a mixture of sulfuric acid and nitric acid), in weak acids (for example, acetic acid) and in the presence of chelating agents (for example, EDTA—ethylenediaminetetraacetic acid). In one embodiment, high metal removal efficiency of 70 to 90% is observed.
