Table 2.

Initial adsorption rate (obtained immediately after +800 mV were applied, dΓ/dt1) and linear approximation of the second adsorption processes (dΓ/dt2, calculated as the linear regression of the data points collected during the last 100 min of the experiment). Errors associated with the adsorbed amount correspond to the error propagation obtained from the thickness values from the ellipsometry experiment and modelled following the procedure described in the article. Errors in the adsorption rates correspond to the standard error in the linear regression calculation.
