最近想用计时安培考察电极表面双电层电容的变化，看了些文献说是用计时安培或计时库仑，但都没有具体的参数设置，我刚刚接触电化学，这方面基本空白，希望各路大虾专家们帮帮我，不胜感激啊！我用的是Epsilon 电分析仪。 以下是我在文献上看到的关于计时库仑测界面电容的一段话，不太明白： Chronocoulometric measurements of the adsorption of the aliphatic compounds were carried out in situ at 0.000Vversus SSCE in an ethanol solution containing NaClO4 (20 mM) and either C12SSO3Na or C12SH (both 1 mM). The potential was stepped from 0.000 to +0.050 V versus SSCE and back for 5 ms.The interfacial capacitance was determined by extrapolating the linear portion of the charge-time curve to zero time and dividing the charge by the potential step.
