Successful design and application of nanoporous materials are essentially dependent on the molecular
diffusion. Two mechanisms, i.e. surface barriers and intracrystalline diffusion, may dominate the mass
transport. In the previous studies, these two mechanisms are difficult to determine with certainty by dual
resistance model [1] (DRM). Here, we derive an expression of uptake rate relying solely on surface
permeability, which provides a method to directly quantify the surface barriers. Subsequently, the effects
of surface barriers and intracrystalline diffusion could be identified separately.
