A semiempirical model for adsorption of binary mixtures

The statistical thermodynamics of polyatomic species mixtures adsorbed on two-dimensional lattices was developed based on generalization of the semiempirical approximation for the adsorption of single components [Romá, F. et al., Langmuir, 2006, 22, 3192–3197]. In this scheme, the partial adsorption...
