Abstract
The adsorption of nitrogen by a carbon black designated as Spheron 9 has been measured at 78K. and 71K. The second type of hysteresis previously reported for three Acheson graphites has also been observed for the adsorption of nitrogen by Spheron 9 at both temperatures. Unlike the graphite isotherms, it was possible to scan the hysteresis loop of the Spheron isotherm. The adsorption of nitrogen has been measured for an artificial graphite in which the ash had been leached out by treatment with hydrofluoric acid. The results were compared with those obtained previously for a sample of the unleached graphite. It was found that although the surface area was altered by this treatment, the hysteresis effects remained unchanged.
