Data for water adsorption at 293 K by an activated series and a heat-treated series of PVDC based carbons are reported. Type 5 (BDDT) isotherms were obtained for adsorption by each carbon. Total water adsorption volumes (a,) are lower than total pore volumes and Dubinin-Radushkevich micropore volume

Two series of activated carbons were prepared from pure polyfurfuryl alcohol and polyvinylidene chloride by gasification with carbon dioxide at 850Β°C. Micropore volumes in these carbons were estimated by adsorption of carbon dioxide (273K) using Dubinin theory, by adsorption of nonane (273K) and by
Three typical samples of active carbons have been investigated by using immersion calorimetry and adsorption techniques (t-plot, t/F method of Dubinin and direct anafysis of the adsorption isotherm before and after prefilling), in order to obtain their external surface area. The different techniques
