Determination of charge transfer and solution resistance. (A) Nyquist representations of the impedance spectra at ~0.6 V vs Ag|AgCl in 10 mM of K4[Fe(CN)6]/K3[Fe(CN)6] in 1 M KCl for VP, HPRS and HPSS electrodes. The measurements were made at a frequency range from 100 kHz to 0.1 Hz with a modulation amplitude of 5 mV. (B) shows a comparison of the charge transfer resistance (Rct), determined by EIS fitting analysis and (C) is a comparison of the uncompensated solution resistance (Rs), also determined from EIS fitting analysis. Statistical analyses were performed using one-way ANOVA followed by a Tukey test. Data are shown as mean ± S.D., n = 4, *P < 0.05 and ***P < 0.001.
