Cation-π Bonding: A New Perspective on the Sorption of Polycyclic Aromatic Hydrocarbons to Mineral Surfaces.

Describes potential cation-pi interactions between pi donors and exchangeable cations accumulated at mineral surfaces via both spectroscopic and batch sorption methods. Sorption of polycyclic aromatic hydrocarbons (PAH) to different minerals saturated with different cations; Molecular interactions of deuterated solutes with mineral surfaces; Sorption mechanism controlling PAH sorption to mineral surfaces.
