Description
Since the discovery of C60 fullerenes in carbon soot extract, scientists have developed a variety of isolation methods. These approaches have included column chromatography (e.g., alumina, charcoal, and silica), HPLC fraction collection, and chemical methods. In this presentation, we have developed a novel purification strategy that uses aminoalkanol to remove fullerene contaminants (e.g., C70, C76, C78, C84) in carbon soot extracts. Once reacted, the contaminants are rendered water-soluble due to the hydrophilic (-OH) functional group. Less reactive and unreactive fullerenes remain in the hydrophobic organic layer. This selective chemical approach permits C60 purity at levels exceeding 99.3%.
