Experimental adsorption isotherms of CO2 adsorbed on several highly gr
aphitized carbon blacks are reported. These data have been analyzed in
order to determine the Henry's laws constants and heats of adsorption
for the systems. The comparison between experiment and theory yields
information concerning the molecule-solid interaction potential. Best-
fit parameters obtained for several versions of the site-site model of
the CO2-graphite interaction are given.
