Web1 nov. 1985 · Cyclic voltammetry of iron electrode in alkaline solution (1 M NaOH) and at elevated temperatures (55–95°C) was performed. The increase in temperature simplifies the voltammograms and makes them invariant in the cyclization time. Web5 nov. 2024 · Practical voltage-scan voltammetry is not simply linear sweep but cyclic voltammetry (CV), at which applied voltage is reversed at a given voltage in the opposite direction. The theoretical evaluation of the voltammogram should be at first represented in the integral form with the time variation and then express the time as the voltage.
