RESUMEN: We will present the results of adsorption
isotherm experiments for Ar, Xe and CF4 on bundles of carbon nanotubes.
The isotherm results will be used to determine the degree of occupation of
the different sets of adsorption sites present on the bundles. The results
will be compared to computer simulations for these systems. Adsorption
isostherm measurements allow the determination of the isosteric heat of
adsorption as a function of coverage. The isosteric heats of adsorption of
the various gases will be presented, and the results will be discussed in
terms of molecular size. We will also present experimental results
regarding the adsorption kinetics for various gases on nanotube bundles,
and we will compare them with recent theoretical calculations.
