Abstract
Adsorption and spectroscopic measurements were performed to determine the n ature of the interaction of organic molecules with the surface of zirconium dioxide. Phenols and carboxylic acids were found to be adsorbed in the ion ic form due to donor-acceptor interactions with surface Zr(IV) ions. Aromat ic amines and heterocyclic nitrogen-containing compound are adsorbed from a queous solution by means of hydrogen bonding with hydroxyl groups on the ox ide surface.
