✦ Synopsis

conductivity, and resistance to UV photodegradation. The The development of surface properties of commercial carbon choice of the carbon black for a given application is much blacks was studied by means of nitrogen adsorption over a wide easier when the properties of the material are well characterrange of pressures. The specific surface area of the samples was ized. In the current work, adsorption-desorption measureevaluated using the standard BET method. The micropore volume ments were used to evaluate the specific surface area, the and external surface area were obtained from the t-plot method.

pore size distribution, and the adsorption energy distribution Distributions of the pore volume and the adsorption energy were for a series of carbon blacks. The specific surface area of calculated numerically by employing the regularization method.

the samples studied was calculated from the BET method It was shown that adsorption measurements provide profound

(2). The t-plot method (3, 4) was used to obtain information insight into the energetic and structural heterogeneity of porous and nonporous carbon materials.
