Abstract
The enthalpies of adsorption and the isotherms for adsorption of napht henic acid onto Na-montmorillonite, Na-kaolinite, and Na-illite were s tudied by means of calorimetry and the static method at 298.15 K. The results show that the enthalpies of adsorption and saturated adsorptio n amounts of naphthenic acid on different clays change in the order Na -montmorillonite > Na-illite > Na-kaolinite. The interaction between n aphthenic acid and clays is discussed. (C) 1997 Academic Press.
