title: The adsorption of water and benzene on amosite and chrysotile asbestos.
abstract: In previous work the authors showed that chrysoltile is more porous than amostie and consequentd benzene with a high molecular cross-section are used as adsorbates. Benzene adsorption is extremely slow on both adsorbents with each point taking from 4 to 24 hours for equilibration. Evidently, the larger benzene molecule has a more difficult ime working its way thrugh the small pores. The water adsorption is predominait. In both cases hysteresis was found. Benzene adsorption on amosite resembled Type IV which relfects capillary condensation phenomena. With chrysotile some chemisorption may have occurred. BET surface areas and heats of adsorption are calculated.
