“…Very similar overall mass balances are applied in the published models, and the majority of these employ the Langmuir adsorption isotherm [1][2][3]5,6,8,9] for describing the non-linear favourable kinetics, typically observed with most proteins. Sophisticated models, taking film, pore, or surface diffusion (or various combinations) into account, have been developed [1,5,6,8].…”
