A B S T R A C T: A number of thermodynamic properties were obtained from the determination of adsorption isotherms and enthatpies of immersion for systems with water and Na- and Ca-bentonites. Entropy differences were calculated by combining the enth

The kinetics of the adsorption of dichloromethane vapour by a typical active carbon have been measured at 288 and 323K and for spherical granules of 0.25 and 1.0 mm in diameter. The data have been analysed within the framework of a model for adsorpti

A combination of techniques—mainly immersion calorimetry and adsorption from the vapor phase—provides independent data for the assessment of micropore sizes and their distribution in relation to parameters E0 and n of the Dubinin-Astahhov (D-A) e

It is shown that there exists a simple relation between the enthalpy of immersion of pure active carbons into water, and the number of so-called primary adsorption sites a0 derived from the water adsorption isotherm by using the new Dubinin-Serpinsky

The adsorption and desorption of water, the layer spacing of the montmorillonite with increasing water content and the heat of immersion with water have been measured for a Na-bentonite and two Ca-bentonites. The bentonite-water system is treated in

The combination of organic vapour adsoprtion and immersion calorimetry, both within the framework of Dubinin's theory, leads to information on the micropore system and the external surface area of activated carbons. Immersion into water appears to gi

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 βE0 of the

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 developme

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 analysis of the adsorption isotherm before and after prefilling), in order to obtain t
