Separation of Polycyclic Aromatic Hydrocarbons by Nonaqueous Capillary Electrophoresis Using Charge-Transfer Complexation with Planar Organic Cations

摘要

In this study, we examine the use of charge-transfer interactions between polycyclic aromatic hydrocarbons (PAHs) and planar organic cations in nonaqueous capil- lary electrophoresis. Since the separations are performed in a purely nonaqueous medium, this method also facili- tates the analysis of solutes that have low solubilities in aqueous or mixed media. Presented in this study are the separations of PAHs as well as the quantitative structure- migration relationships that assisted in achieving a better understanding of the forces through which the PAH molecules interact with the acceptor cation.
