The fitting of the adsorption data for Trp in Case 2 with the linearized forms of the seven adsorption models (a) Langmuir, (b) Freundlich, (c) Temkin, (d) Kiselev, (e) Elovich, (f) Fowler–Guggenheim and (g) Hill–de Boer. The small circles are the data derived from simulation results and the lines are calculated using the linearized expressions with fitted parameters.
