Calculation of adsorption energy and Henry law constant for nonpolar molecules on a nonpolar uniform adsorbent
Article Abstract:
Experiments were performed to investigate van der Waals interactions was presented. The interaction between an adsorbed molecule with a uniform adsorbent in hydrocarbons and other compounds on graphite was investigated. Moreover, the adsorption properties such as the molecule area on the adsorbent, adsorption energy and the Henry law constant were described. The findings demonstrate that generalized charges for hydrogen and oxygen atoms facilitate the calculation of molecular areas and adsorption potential energies.

Characterization of specific N(sub 2)-adsorption site existing on CuZSM-5 type zeolite: effect of ion-exchange level on adsorption properties
Article Abstract:
The specific dinitrogen-adsorption site found in copper-ion-exchanged ZSM-type zeolite (CuZSM-5) has been investigated using emission and infrared spectroscopy and by measuring heat of adsorption and adsorption isotherms of dinitrogen and carbon monoxide. An intense band appears at 2295 cm (super -1) in the infrared spectra, which is apparently induced by the adsorbed dinitrogen species. The amount of both adsorbed carbon monoxide and dinitrogen increases as the copper-ion-exchange level of ZSM-5 sample increases.
