The problem of adsorption at low coverage N on a fractal surface is addressed. General, but approximate, arguments are presented to show how the fractal dimension D is related to the Henry's-law coefficient of proportionality between N and the pressure. A semiclassical analysis validates this relation at high temperature. An evaluation for a regular fractal surface demonstrates this behavior explicitly. Relation is made to a fractal Brunauer-Emmett-Teller theory of multilayer adsorption.
