研究了 1,6-二氯己烷 (1,6-DCH) 和 1,4-二氯丁烷 (1,4-DCB) 作为有机溶剂 (O) 在 O|水 (W) 界面离子转移伏安法中的有用性，并将结果与 1,2-二氯乙烷 (1,2-DCE) 进行了比较。 0.1M 四辛基铵四(4-氯苯基)硼酸盐(O)|0.05M Li2SO4(W)界面的电位窗宽度按顺序增加：O = 1,6-DCH > 1,4-DCB > 1,2-DCE。各种阳离子和阴离子在1,6-DCH|W和1,4-DCB|W界面处转移的伏安行为已被证明具有可逆性，并且已确定了中点电位或可逆半波电位。亲水离子的中点电势也已通过分析具有O|W界面的伏安图的阳极最终上升或阴极最终下降来确定，其中W包含亲水离子的盐。此外，还讨论了 O 中离子对形成对中点电位的影响。
The 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-dichloroethane (1,2-DCE). The width of potential window of the 0.1M tetraoctylammonium tetrakis(4-chlorophenyl)borate (O)|0.05M 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|W 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. Also, the effect of ion-pair formation in O on the midpoint potentials has also been discussed.
