A pair of symmetrical cathodic and anodic peaks is observed in cyclic voltammograms for the ion transport across a bilayer lipid membrane (BLM) between two aqueous phases in the presence of tetraphenylborate (TPhB). Although TPhB serves as a carrier of a hydrophilic counter ion (Na) under the steady-state condition, the reason for the appearance of symmetrical peaks has not been clearly explained until now. From the chronoamperometric analysis, it is turned out that the symmetrical peaks are attributed to the translocation of TPhB between two adsorbed layers on the surface of the BLM.
在含有四苯硼（TPhB）的两相水溶液之间的双层脂质膜（BLM）中，观察到离子跨膜传输的循环伏安图中出现一对对称的阴极和阳极峰。尽管 TPhB 在稳态条件下作为亲水性抗衡离子（Na）的载体，但对称峰出现的原因至今仍未得到明确解释。通过计时安培分析，发现对称峰归因于 TPhB 在 BLM 表面吸附层之间的转运。
