Abstract
Differential heats of adsorption have been measured calorimetrically for benzene and n-hexane on AlPO4-5. Adsorption isotherms have been determined for benzene, n-hexane and H2O. The heat of adsorption for benzene on AlPO4-5 was found to be less than the heat of adsorption for n-hexane. Isotherms of all adsorbates investigated exhibited hysteresis loops. The hydrophilicity of AlPO4-5 is explained by capillary condensation and/or coordinately bonded water.Keywords
