Description:
The goal of this work is to develop sampling and analytical methodologies for extracting and quantifying fullerenes in aqueous colloidal suspensions. Sampling and analysis of colloidal suspensions pose some unique challenges not encountered when working with true solutions. For example, sampling and analysis of aqueous fullerene suspensions is made problematic by the difficulty of preparing a standard suspension of known analyte concentration. As a result, extraction recoveries can be best determined through exhaustive extraction to determine total analyte mass in suspension.
