“…Here, at low frequencies, E p is shifted negatively with increasing f; at frequencies between 10 and 20 Hz, E p varies abruptly, and for frequencies larger than 20-25 Hz, E p remains essentially constant. This variation is similar to that described theoretically for thin mercury film electrodes [51], and parallels the response recorded for 4,4 0 -bipy- ridinium ions covalently attached to MCM-41 [52]. For BTP@MCM the peak potential of peaks IIa, IIb is almost f-independent, as expected for a diffusion-controlled reversible process [48].…”

“…(6) Full Paper tials, as expected, and the peak height increased markedly. As it has been reported in the literature [38], it was found that, for the case of thin mercury films, the peak potential shifted slightly toward more negative potentials with decreasing film thickness in the expense of the increased peak height, until a maximum value of current is reached. Thus, an optimum film thickness of 2.2 micron was used in order to get higher peak intensities while providing a good mechanical adhering of the mercury film.…”

“…Concerning the trend of E p vs. log , the theory predicts for a TMFE an approximately linear behaviour with a slope, for nE sw = 50 mV, of +59.2 mV per log unit [98]. This implies that: in the case of n = 2 the predicted slope for E SW = 25 mV is +29.6 mV/log unit, while in the case of n = 1 the predicted slope for E SW = 50 mV is +59.2 mV/log unit.…”
