Abstract

Actually, the characterization of the purity of fullerenes is mainly based on the concept of defining the percentage amount of the main component (e.g. C60, C70, etc.) versus the minor- or micro-fractions of the homologue species and/or other polycyclic organic compounds. But, it has also to be considered that fullerene products may be contaminated in some degree by element impurities as well originated both from the production processes and from the various precursor materials themselves. We are reporting here for the first time detailed data on trace element impurities in various fullerene precursors as well as in the main C60 and C70 fullerene products of different producers measured by instrumental neutron activation analysis (INAA). The concentration distributions of about 35 trace elements have been studied including the determination of the relevant limits of detection (LoD) values concerning the experimental conditions applied to the analysis. It could be established that all fullerene materials investigated contain a broad scale of trace elements distributed within a fairly wide concentration range from ppb (ng/g) up to ppm (μg/g) levels. For some impurity elements extremely high concentration levels were found indicating that elemental impurities have to be considered when studying the electrical, magnetic and other features of the fullerenes.
