Modelling of water adsorption by activated carbons : effects of microporous str...
Abdou Slasli; Miguel Ângelo da Silva Jorge; Fritz Stoeckli; Nigel SeatonThe present paper examines the adsorption of water by microporous carbons containing various amounts of surface oxygen and a smaller proportion of basic centres. The modelling of water adsorption for 293 and 310 K, using variable pore size distributions (PSD), confirms that the overall type IV isotherm is the sum of a type I isotherm associated with the specific interactions, and a type V isotherm reflecting th...
Water adsorption by activated carbons in relation to their microporous structure
Abdou Slasli; Miguel Ângelo da Silva Jorge; Fritz Stoeckli; Nigel SeatonThe present paper examines the adsorption of water by microporous carbons in the absence of specific interactions. The modelling of water adsorption for 293 and 310 K, using variable pore size distributions (PSD), shows that the type V isotherms follow the Dubinin-Astakhov (DA) equation and fulfill the requirement for temperature invariance. Furthermore, the parameters of the DA equation can be related in a sim...
