“…This is due to the reversible behavior of the ion transfers which take place in both interfaces of the liquid-liquid membrane. For these reasons SWV technique is an excellent tool for analyzing the reversibility of charge transfer processes [27]. It can be also observed from the same figure that the square wave signal obtained in Figure 1b is formally similar to that obtained when only one interface is considered, whereas that obtained in Figure 1c presents a sharp fall at negative potentials.…”

“…This irreversible system gives rise to a peak (on the differential current voltammogram) due to the SWV waveform as it was shown by Daniel et al [42] and confirmed by the analysis of the individual forward and reverse SWV currents by Fatouros and Krulic [43].…”

“…For the electrochemically reversible system, the peak potentials of the forward and reverse scans in the SWV experiments are the same and equal to E 1/2 (Ox/Red). [10,18] The reason for such a peak-potential difference can be the IR drop (potential drop due to the solution resistance). The influence of the IR drop in SWV can be described by a complex dimensionless resistance argument 1, [19] as shown in Equation (1):…”

“…Therefore, the influence of the IR drop on the SWV measurements can be omitted in our case and other reasons (e.g. slow electron-transfer kinetics) [18] should be considered for the peak-potential difference of Fc/Fc + . Therefore, Fc/Fc + was not acceptable as reference couple in our SWV studies, and thus, we used the DmFc/ DmFc + couple.…”
