Abstract A direct adsorption kinetic study of an unbleached Kraft woodpulp has... [Pg.353]

If one assumes that at the same level of relative humidity and degree of hydrophilic character of the substrate the number of layers of adsorbed water molecules is independent of the substrate, this number might correspond to seven . Accepting as a good approximation that the molecular area of water molecules is 20x10" m (20 A ), then the initial surface area obtained for this unbleached woodpulp would be 2.5x10 m g". ... [Pg.355]

The value hereby derived for the initial surface area of the studied woodpulp is of the same order of magnitude of surface areas for unbleached woodpulps already published (=2.5xl(F m g- ) ", and based upon nitrogen adsorption studies. Although in need of a refinement in terms of experimental technique, this approach clearly reveals an outstanding potential for surface area determination of paper woodpulps. [Pg.356]
