Adsorption and collective diffusion of interacting particles on one- dimensional heterogeneous substrates are studied by Monte Carlo (MC) simulation. The collective difusión coefficient is determined by employing the Kubo- Green theory, trough the jump difusión coefficient and the thermodynamic factor. The correlated hetrogeneous substrate is generated though the Dual Site- hond Model, considering two limit topograohies: random and high correlated surface topographies. A rich variety of different behaviors is found and analyzed in the framework of the lattice gas model.
