Abstract

Actually the purity of fullerenes is in general characterized as the percentage of the main component (e.g. C60) versus the higher fullerenes (e.g. C70, etc.) and/or in a few cases of some other polycyclic organic components. We are reporting here for the first time detailed data on trace element impurities in fullerene precursors and in the main fullerenes. For studying the element impurities instrumental neutron activation analysis (INAA) was used. Our measurements have shown that all these materials contain trace elements at ppb (ng/g) and ppm (ug/g) levels. From the results it comes out that in the future investigations of the elemental purity of the C60 and C70, and even of the higher fullerenes would have to be also considered when their electrical, magnetic, etc. properties are studied.
