近来,本文作者发现在1N Na_2SO_4 及其用正庚醇饱和的溶液中所测得的汞电极微分电容曲线和Grahame经典文献中数据不符。经过仔细分析,发现Grahame文中有关曲线的电势横坐标不应是原文中的“相对于当量甘汞电极,而应换成“相对于当量硫酸亚汞电极”。改正以后,Grahame和本文作者的结果符合良好(见下图)。

Recently, the authors found that the curve of the mercury electrode differential capacitance measured in 1 N Na 2 SO 4 and its solution saturated with n-heptanol did not agree with the data in the Grahame classics. After careful analysis, it is found that the abscissa of the potential of the curve in Grahame’s text should not be “relative to the equivalent calomel electrode but to” relative to the equivalent calomel electrode. "After correction, the results of Grahame and the authors In line with good (see below).
