“…The results of measurements of potential of zero charge E z for the system BU-pT and BU-mT described in [1] indicate distinct shift of the value E z towards the negative values but only at their lowest concentrations, a further increase of concentration of both isomers causes slow shift of the value E z towards the positive potentials but these changes are much smaller compared with those occurring with the increase of BU concentration in 1 M NaClO 4 . This behavior suggests that at lower concentrations, toluidine molecules have flat orientation on the mercury surface enabling interaction of b electrons of the aromatic ring with the electrode surface.…”

“…Electroreduction of Zn 2 ions from NaClO 4 solutions at a mercury electrode in the presence of p-toluidine (pT) or m-toluidine (mT) and 1-butanol (BU) is claimed to involve two consecutive oneelectron transfer steps in the overall reaction. Furthermore, as the reaction involves charged reactants in the double layer, double layer effects are expected to be important in these processes.…”

Influence of the Mixed Adsorption Layer of 1‐Butanol/Toluidine Isomers on the Two Step Electroreduction of Zinc(II) Ions

Studies of mixed adsorption layers with respect to their influence on kinetics of Zn 2 ions reduction indicate dynamics of this process in the presence of inhibitor and accelerating substances. This effect can be seen as a much greater increase of standard constant rates compared with a similar increase without the inhibitor. 1-Butanol was used as an inhibitor in the studies and p-toluidine and m-toluidine as accelerating substances. The adsorption measurements show that in the range of Zn 2 ion reduction potentials in the solutions containing 1-butanol and the definite isomer of toluidine, toluidine plays a dominant role in establishing equilibrium in the mixed adsorption layer. The obtained values of the true standard constant rates of the transfer of the first electron k s1 t and the second electron k s2 t indicate that in each of the studied systems the stage of the first electron transfer is more strongly accelerated compared with the stage of the second electron transfer. The linear character of the dependence k s1 t and k s2 t in the function of the surface excess and in the function of 1-butanol concentration indicates that active complexes are formed for each case of the mixed adsorption layer.

“…The electron transfer mechanism, reactions [2] and [3], does not seem to be probable because it suggests formation of a neutral zinc atom, in solution (close to the 0.H.p.) that diffuses only towards the electrode surface.…”

MARILEA MANZINI and ANDRZEI LASIA. Can. J. Chem. 72, 1691 (1994). The electroreduction of Zn' + was studied in propylene carbonate (PC), acetonitrile (ACN), and hexamethylphosphorarnide (HMPA) on mercury at various concentrations of tetraethylammonium perchlorate as a supporting electrolyte using dc polarography, cyclic voltammetry, chronoamperometry, and ac polarography. It was found that in PC and ACN the electroreduction process proceeds in one step. In HMPA, however, the electroreduction proceeds through a CEE mechanism in which a chemical reaction is followed by a charge transfer in two steps. The heterogeneous rate constants, corrected for the double layer effects, decrease with increase in the solvent donor number. The electroreduction process proceeds through the cation transfer mechanism.MARILEA MANZINI et ANDRZEJ LASIA. Can. J. Chern. 72, 1691 (1994).

“…One is to extrapolate the exchange current from data at low concentrations such as the work of Hurlen et al [65,[71][72][73], where the io is three orders of magnitude smaller, the other is to measure the growth rate of a single, uniformly active surface such as the tip of a dendrite. The second method, used by Landau [48], yields an exchange current density of over 250 mA/cre 2. lt may overestimate the real value, however, since the ohmic drop is changing as the dendrite grows toward the counter electrode.…”
