โœฆ Synopsis

method of determining the main parameters of the micropore structure of activated carbons is proposed, based on Dubinin's theory of micropore filling, but using data from immersion calorimetry and water vapor adsorption at different relative pressures pips.

The combination of gas-solid adsorption experiments with immersion calorimetry of carbons into liquids of increasing molecular dimensions leads to accurate micropore distributions in the range 0.4-0.8 nm. This technique is used to study the development of the micropore structure during activation of

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.

Two series of activated carbons were prepared from pure polyfurfuryl alcohol and polyvinylidene chloride by gasification with carbon dioxide at 850ยฐC. Micropore volumes in these carbons were estimated by adsorption of carbon dioxide (273K) using Dubinin theory, by adsorption of nonane (273K) and by

## It is shown that an exact expression can be derived from Dubinin's theory, for the enthalpy of immersion of active carbons. It appears that for a given liquid, the specific enthalpy of immersion is a function of the characteristic energy REo of the Dubinin-Astakhov equation. The new relation is
