Abstract

Adsorption isotherms have been determined for the system [water (1)–methanol (2)] on graphitised carbon (Graphon) at five temperatures in the range 298.15–338.15 K, and for the system [water (1)–ethanol (2)]/Graphon at six temperatures from 298.15 to 348.15 K. The data have been subjected to a thermodynamic analysis to obtain values of the interfacial tension at the liquid/solid interface and for the enthalpy and entropy of immersion of Graphon into liquid solutions, relative to the corresponding quantities for one or other of the pure components.
