摘要：

It is proposed that adsorption isotherms of water vapor determined on non-porous carbons can be classified into four distinct types, and that a certain level of polarity and distribution of polar sites is associated with each. Examples of each water isotherm type have been obtained by modification of the non-porous non-graphitized carbon black Elftex 120. In addition, certain features of the results, related to the adsorption of water vapor by microporous carbons, are considered. It is clear that the uptake of water vapor at 0.6p-degrees is not related to the surface area of the micropores. On the other hand, the results do suggest that polar sites are located at the entrances to micropores.
