Adsorption of a strongly bound absorbate in a bidisperse‐pore system is modeled using a Turner pore structure. This idealized system leads to an analytical solution for the micropore uptake of adsorption that is valid for a part of the adsorption‐time profile. The analytical solution yields a well‐defined criterion that establishes the boundary between an adsorption process dominated by macropore resistance and one dominated by micropore resistance. The range of the analytical solution is extended to include the entire adsorption‐time profile using an approximate analytical solution and two asymptotic solutions.
