MONTE-CARLO STUDY OF MULTILAYER ADSORPTION ON SURFACES WITH PREADSORBED PARTICLES

The Monte Carlo simulation method is used to investigate multilayer adsorption of a volatile gas in the presence of a preadsorbed, nonvolatile, layer. It is shown that the proposed algorithm leads to results demonstrating that the predicted mechanism of multilayer formation is in a good qualitative agreement with experimental data obtained for krypton adsorption on graphite preplated with carbon tetrachloride. The influence of the relative magnitudes of the parameters describing various types of molecular interactions in the system on the mechanism of multilayer formation is also discussed.
