Stripping voltammetry

Japanese: stripping voltammetry(英語表記)strippingvoltammetry
Stripping voltammetry

...By stirring the electrolyte, rotating the electrode at a constant speed, or moving the electrolyte with a pump, the amount of the substance to be electrolyzed that diffuses to the electrode increases, which can increase the sensitivity of the analysis and the yield of synthesis by electrolysis, and is sometimes called convection voltammetry. The method of concentrating the substance to be electrolyzed by electrolytic deposition on the electrode and then applying a reverse potential to record the voltammogram is called stripping voltammetry (Figure 2-f). An electrode that uses a mercury drop suspended at the end of a platinum or glass capillary tube is called a hanging mercury drop electrode, and the method of electrolytically depositing metal on this electrode to form an amalgam and recording a stripping voltammogram is used as an ultramicroanalysis method because it can quantify trace amounts (for example, 10 -9 to 10 -10 mol/l) of metal ions such as Pb 2+ and Cd 2+ . ...

Japanese:

…電解液をかきまぜたり,電極を一定の速度で回転させたり,あるいはポンプで電解液を動かすことによって対流を起こすと,電極に拡散する被電解物質の量が多くなり,分析の感度を高めたり,電解による合成の収率を上げることができ,対流ボルタンメトリーconvection voltammetryと呼ばれることがある。被電解物質を電極に電解析出させて濃縮し,ひきつづき逆電位をかけてボルタモグラムを記録する方法はストリッピングボルタンメトリーstripping voltammetryといわれる(図2‐f)。白金やガラス毛細管の先に水銀滴を懸垂させて用いる電極をつり下げ水銀滴電極といい,この電極に金属を電解により析出させてアマルガムとし,ストリッピングボルタモグラムを記録する方法は,痕跡量(たとえば10-9~10-10mol/l)のPb2+,Cd2+などの金属イオンを定量できるので超微量分析法として利用されている。…
