Voltammetry applies a constant and/or varying potential at an electrode's surface and measures the resulting current with a three-electrode system. This method can reveal the reduction potential of an analyte and its electrochemical reactivity. This method, in practical terms, is non-destructive since only a very small amount of the analyte is consumed at the two-dimensional surface of the working and auxiliary electrodes. In practice, the analyte solution is usually disposed of since it i… WebChronoamperometry profiles for the AG-HGPE and wet GF separator in the Zn//Zn symmetric cells at room temperature with a step potential of 10 mV Insets are the Nyquist plots of the two Zn ...
