Abstract
We apply the replica methodology and the replica Ornstein-Zernike equations to calculate adsorption isotherms on an energetically heterogeneous surfac e. The surface is modeled by quenching a two-dimensional "fluid of centers. " After the quenching, we study gas adsorption using the replica Ornstein-Z ernike equation with the hypernetted chain closure. The results of theoreti cal predictions are compared with the data obtained from the Grand Canonica l Monte Carlo simulation, and the obtained agreement is satisfactory. (C) 1 999 Academic Press.
