Isotherms for the adsorption of carbon dioxide and of water vapor by two paper pulp samples, one slightly beaten and one well beaten, have been observed over a range of temperatures. Heats of adsorption and area of surface concerned have been calculated. For water vapor, the heats of adsorption and the surface area are essentially equal for both pulps. For carbon dioxide, the heat of adsorption is greater and the area is smaller for the well beaten than for the slightly beaten pulp.
