Abstract
The adsorption of 2,2'-bipyridine onto loughlinite (Na-sepiolite) has
been investigated by FT-IR and micro-Raman spectroscopy. Spectroscopic
results indicate the formation of monoanionic surface species.
Most of the adsorbed molecules are incorporated in the channels of the
clay structure and coordinated to Lewis acidic centers directly or indirectly
through water molecules.
