The main purpose of this paper is to develop the equations for the half-wave potentials of facilitated proton transfer or protonated species transfer across liquid|liquid interfaces, explicitly considering the water autoprotolysis equilibrium. The main equation developed in this article allows simulating different chemical systems, which are compared to simulated results using a previously developed model (J. Electroanal. Chem. 578 (2005) 159–170). Both the effect of the initial concentration of the weak base and the volume ratio of the aqueous to organic phases on the half-wave potentials are presented. Finally, approximate equations are developed that allow not only to adequately justify the behaviour of the half-wave potentials with the volume ratio and the initial concentration of the weak base, but can also be used as a tool to explain or predict experimental results.

本文的主要目的是明确考虑水的自质分解平衡，建立促进质子转移或质子化物质跨液界面转移的半波势方程。本文开发的主要方程式允许模拟不同的化学系统，并使用先前开发的模型将其与模拟结果进行比较（J. Electroanal。Chem。578（2005）159-170）。给出了弱碱的初始浓度和水相与有机相的体积比对半波电势的影响。最后，建立了近似方程，不仅可以用弱比的体积比和初始浓度来充分证明半波电势的行为，
