Where I work, we are setting up a series of studies concerning the adsorption & desorption (out gassing) of a certain component in several types of materials, & I have been tasked to formulate models of the process. I have noted that in my research so far that the models in the literature (Langmuir, etc.) do not seem to consider diffusion as part of process. Can someone explain to me why it's left out of the discussion?
