JOURNAL FREE ACCESSThe characteristics of the three components composing the liquid function potential (LJP) between electrolyte solutions in different solvents have been reviewed based on the results obtained by the author and his coworkers. The results by the author's group are briefly compared with those by other research groups. Some of the supposed dynamic aspects that may influence the characteristics of the LJP arediscussed. In connection with this, the transient behavior of the LJP between solutions in the same solvent is outlined.View full abstractDownload PDF (3263K) -

JOURNAL FREE ACCESSThe usefulness of 1, 6-dichlorohexane (1, 6-DCH) and 1, 4-dichlorobutane (1, 4-DCB) as organic solvent (O) for ion-transfer voltammetry at O | water (W) interface has been examined, and the results are compared with those with 1, 2-dichioroethane (1, 2-DCE). The vapor pressure of 1, 6-DCH is very low (6 Pa at 25 °C), indicating that the solvent is useful for the O-phase particularly from the viewpoint of practical applications. The width of potential window of the 0.1 M tetraoctylammonium tetrakis(4-chlorophenyl)borate (O) | 0.05 M Li2SO4 (W) interface increased in the sequence: O = 1, 6-DCH > 1, 4-DCB > 1, 2-DCE. The voltammetric behavior of the transfer of various cations and anions at the 1, 6-DCH | and 1, 4-DCB | W interfaces has been shown to be of reversible nature, and the midpoint potentials or the reversible half-wave potentials have been determined. The midpoint potentials of hydrophilic ions have also been determined by the analysis of anodic final rise or cathodic final decent of the voltammograms with the O | W interfaces, where the W contains a salt of the hydrophilic ion. The effect of ion-pair formation in O on the midpoint potentials has been discussed. The usefulness of 1, 6-DCH for voltammetry of electron-transfer at O | W interface has also been discussed.View full abstractDownload PDF (1949K) -

JOURNAL FREE ACCESSElectrochemical study on ion transports from one aqueous (W1) to another (W2) across a liquid membrane (LM) and a bilayer lipid membrane (BLM) is reviewed. The ion transport across a membrane (M) consists of the ion transfers at W1|M and M|W2 interfaces and the ion migrations within W1, M and W2. In the presence of sufficient electrolytes in W1, M and W2, the membrane transport is demonstrated to be controlled by the complementary ion transfers at W1|M and M|W2 interfaces. The authors found that various phenomena observed with the ion transport across the BLM could be elucidated by taking into account the conjugated ion transfers at W1|BLM and BLM|W2 interfaces. The relation between the waveforms of voltammograms and physicochemical properties of added ion, coexisiting ions, lipids composing BLMs and ligands forming complexes was also clarified.View full abstractDownload PDF (2935K) -
