Convection voltammetry

...The pattern of the CV voltammogram varies significantly depending on the type of reaction, and the reaction rate, activation energy, molecular orbital parameters, etc. can be determined by analyzing the lineshape in the usual way. By stirring the electrolyte, rotating the electrodes at a constant speed, or moving the electrolyte with a pump, the amount of the electrolytic substance 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 electrolytic substance by electrolytic deposition on the electrode and then applying a reverse potential to record the voltammogram is called stripping voltammetry (Figure 2-f). ...

…CVのボルタモグラムは反応の形式によりそのパターンが著しく異なり,その線形を常法に従って解析することにより反応速度,活性化エネルギー,分子軌道パラメーターなども求めることができる。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)。…
