研究了以MgSO_4为支持电解质的水溶液（W）和以稀离子i ~+和j ~+·Y ~-为支持电解质的有机溶液（CH_3）之间界面电位差的振荡.所用的振荡介质为Cs ~+四苯基硼酸四戊铵（TpenA ~+·TPhB ~-）在硝基苯（NB）中，四甲基铵离子+ TPenA ~+·TPhB ~-在硝基苯（NB）中，W ~+四苯基胂二苦胺盐（TPhAs ~+·DPA）在1，2-二氯乙烷中等。根据伏安曲线和界面电毛细曲线，考虑到离子对（i+·Y-）在电介质中的形成平衡，阐明了振荡的振幅、周期、脉宽和可供振荡的电流范围等特征，并提出了振荡的机理。强调了i ~+·Y ~-在界面上的吸附-脱附和脱附后i ~+·Y ~-的解离的重要作用。
The oscillations of potential difference at the interface between an aqueous solution (W) containing MgSO4 as a supporting electrolyte (SE) and an organic solution (Org) containing dilute ion i+ and j+•Y- as SE were investigated by forcing the transfer of i+ at the interface through an applied current. The Org employed were Cs+tetrapentylammonium tetraphenylborate (TpenA+•TPhB-) in nitrobenzene (NB), tetramethylammonium ion + TPenA+•TPhB- in NB, W++ tetraphenylarsonium dipicrylaminate (TPhAs+•DPA) in 1, 2-dichloroethane, etc. The necessary conditions for the oscillation were confirmed to be identical to those for the appearance of the maximum in the voltammogram for the transfer of i+ at the interface. By referring to the voltammogram and the electrocapillary curve at the interface and taking into account the ion pair (i+•Y-) formation equilibrium in Org, such characteristics of the oscillation as the amplitude, period, pulse width and range of the applied current available for the oscillation were elucidated, and a mechanism for the oscillation is proposed. The important roles of the adsorption -desorption of i+•Y- at the interface and the dissociation of the desorbed i+•Y- were emphasized.
