Kinetics modelling. (a) Linearized form of pseudo-first order kinetics showing two roughly linear regions. (b) Reaction rate constants for first (k1−1) and second (k1−2) pseudo-first order kinetic processes identified in (a), shown with exponential fits. Error bars correspond to linear fitting errors. (c) Linearized form of the pseudo-second order kinetics showing highly linear behavior (r2 > 0.998). (d) Top panel: comparison of Site-2 occupancy (\({\theta }_{2}\)) as estimated from pseudo-first order kinetic and double exponential models. Bottom panel: percent difference (|ΔMe|) between measured equilibrium mass (\({M}_{e}\)) and equilibrium mass predicted by pseudo-first order, pseudo-second order, and double exponential kinetic models. Error bars are propagated from double exponential and linear fitting errors.
