There are several types of working electrodes for dissolution voltammetry

The working electrodes of the dissolution voltammetry method are usually categorized into two types: mercury electrodes and non-mercury electrodes. Mercury electrodes, including suspended mercury electrodes and mercury film electrodes, are one of the most commonly used working electrodes. Suspended mercury electrodes are formed by liquid mercury drops or columns in contact with an external solution, and can be adapted to a variety of electrochemical reactions of different natures.

Non-mercury electrodes, on the other hand, include carbon electrodes, gold electrodes, platinum electrodes and so on. Carbon electrodes are made of carbon materials with good electrical conductivity, high chemical stability, low background current and good reproducibility.
