✦ Synopsis

The enthalpies of adsorption and the isotherms for adsorption point, about 30ЊC; boiling range, 160-198ЊC; specific gravof naphthenic acid onto Na-montmorillonite, Na-kaolinite, and ity, 0.982 g cm 03 ). Its elemental composition is 75.94% C, Na-illite were studied by means of calorimetry and the static 10.66% H, and 13.40% O, and the average molecular weight method at 298.15 K. The results show that the enthalpies of adis 237, which was measured in this laboratory. Na-montmosorption and saturated adsorption amounts of naphthenic acid on rillonite (SWy-1), Na-kaolinite (KGa-2), and Na-illite were different clays change in the order Na-montmorillonite ú Naobtained from the Source Clays Minerals Repository, Deillite ú Na-kaolinite. The interaction between naphthenic acid and

The adsorption enthalpy and the adsorption isotherm of tetradecylpyridinium bromide (TPB) onto a Na-montmorillonite suspension and the dilution enthalpy of the TPB solution have been determined at 298.15 K. The dilution process is endothermic and the adsorption process is exothermic. For ion exchang
