…Voltammetry uses an indicator electrode (working electrode) such as platinum, mercury, or carbon to perform electrolysis, and obtains information about various chemical phenomena, especially redox reactions, that occur at the electrode-solution interface from the resulting current-potential curve (voltammogram). The term voltammetry is a general term given by the Dutchman Izaak Mauritis Kolthoff (1894- ) to electrochemical techniques that are primarily potential-regulated, including polarography. The standard for potential is the saturated calomel electrode (abbreviated as SCE) or the silver-silver chloride electrode (Ag/AgCl), which show stable values even when a small current flows. … *Some of the terminology that mentions "polarography" is listed below.

…ボルタンメトリーは白金,水銀,カーボンなどの指示電極(作動電極)を用いて電気分解を行い,そのときの電流‐電位曲線(ボルタモグラム)から電極‐溶液界面で起こる種々の化学現象,とくに酸化還元反応に関する情報を得る。 ボルタンメトリーという呼称は,ポーラログラフィーpolarographyを含む主として電位規制の電気化学的手法に関して,オランダのコルトホフIzaak Mauritis Kolthoff(1894‐ )が与えた総称である。電位の基準は,微小の電流が流れても安定な値を示す,飽和甘汞(かんこう)電極saturated calomel electrode(SCEと略称),銀‐塩化銀電極(Ag/AgCl)などが用いられる。… ※「polarography」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
