✦ Synopsis

The adsorption isotherms of N, at 77K, CO, at 251, 273 and 298K, and SO, at 262 and 273K have been determined on a series of physically activated carbons with a wide range of micropore size distributions. Since the series includes carbons with very high burn-off, it shows the problems involved in the characterization of microporsity in superactivated carbons. On the other hand, the results show that the carbon surface-adsorbate interactions for SO, at low relative pressures are weaker than for N, and CO,, as a result of the strong adsorptive-adsorptive interactions in the bulk gas phase.

The adsorption and the desorption of SO: on active carbons is studied in relation to the surface characteristics of the carbons. Surface basic groups (with pyronic or pyronic-like structure) greatly increase the adsorption of SO,, that can be divided into two forms. one weakly and the other strongly
