dropping mercury electrode

Experiments run with dropping mercury electrodes are referred to as forms of polarography.

Polarography is the measurement of voltammetry at the dropping mercury electrode.

Polarometry is a subclass of voltammetry that uses a dropping mercury electrode as the working electrode.

Dropping mercury electrode (DME)

In the previous method, a voltage was applied to a dropping mercury electrode and a reference electrode was immersed in a test solution.

The dropping mercury electrode (DME) is a working electrode made of mercury and used in polarography.

Polarography - a subclass of voltammetry where the working electrode is a dropping mercury electrode (DME), useful for its wide cathodic range and renewable surface.

The hanging mercury drop electrode (HMDE) is a working electrode variation on the dropping mercury electrode (DME).

What makes polarography different from other linear sweep voltammetry measurements is that polarography makes use of the dropping mercury electrode (DME) or the static mercury dropping electrode.

Electrocapillarity or Electrocapillary phenomena are the phenomena related to changes in the surface energy (or interfacial tension) of the Dropping mercury electrode (DME) as the electrode potential changes or the electrolytic solution composition and concentration change.

The hanging mercury drop electrode (HDME) produces a partial mercury drop of controlled geometry and surface area at the end of a capillary in contrast to the dropping mercury electrode (DME) which steadily releases drops of mercury during an experiment.

An earlier polarographic investigation of rhodocenium perchlorate at neutral pH showed a cathodic wave peak at 1.53 V (versus SCE) at the dropping mercury electrode, corresponding to the formation rhodocene in solution; however, the researchers were unable to isolate the neutral product from solution.
