✦ Synopsis

Abstrart-The surface properties of activated carbon are characterized by their surface acidity, surface ash content and elemental composition. The surface acidity of activated carbon can be readily determined by alkalimetric titration and calculated by the Gouy-Chapman theory of electrical double layer. Electrophoretic mobility measurement provides little information on the nature of the acidity of the activated carbons. No correlation can be deduced between the surface chemical composition and the acidity.

A method for characterization of carbon surfaces' acidity using a continuous distribution of acidity constants is proposed. The method is based on potentiometric titration measurements. Titration curves are transformed into proton adsorption isotherms, and are analyzed to yield the distribution of a

Nitrogen adsorption isotherms on activated carbon fibers (ACFs) were measured at 77.3 K in the relative pressure range from 10(-7) to 0.995. The low relative pressure data are examined in detail in order to characterize the microporosity and the surface heterogeneity of the samples studied. The pore

Seventeen kinds of activated carbons of different surface acidity and of known pore-structure were used as adsorbents for gas chromatography. The retention time of various kinds of substrates was determined for each carbon at different temperatures. It was found that surface acidity of carbons has a
