Abstract :
Dubininʹs theory, developed in successive stages between 1947 and 1971 and extended to immersion calorimetry in the 1980s, has recently found new applications. It has been shown that water adsorption by microporous carbons, corresponding to type IV and V isotherms, can be described by the Dubinin-Astakhov (D-A) equation. The extension to immersion calorimetry is also valid and provides information on the interaction between water and oxygen-containing surface groups. The D-A equation has also been combined successfully with the theory of Myers and Prausnitz, which leads to a satisfactory description of static and dynamic adsorption of binary mixtures by active carbon beds.
