Abstract
Experimental data for adsorption at the solution/Graphon interface from the systems benzene + cyclohexane, benzene + heptane and cyclohexane + heptane are presented and analysed in terms of the Gibbs adsorption isotherm. The data for the three systems are shown to be thermodynamically mutually consistent. The surface excess isotherms may be described with reasonable accuracy in terms of simple statistical thermodynamic monolayer models. Evidence is found that the molecular interactions which lead to non-ideality in the bulk phase are much less pronounced in the adsorption region.Keywords
