Abstract
The adsorption of 4,4'-bipyridyl by natural attapulgite from Anatolia (Turkey) has been studied using vibrational spectroscopy. Investigatio ns of Fourier-transform infrared and Fourier-transform Raman spectra o f adsorbed 4,4'-bipyridyl indicate the presence of physical and chemic al sorbed surface species. No anionic surface species has been observe d. It is proposed that chemisorbed 4,4'-bipyridyl molecules are coordi nated to either Lewis acidic centers or surface hydroxyls as monodenta te ligands.
