Answer:
Dropping Mercury Electrode (DME)
Polarography
Polarography is one of the Voltametric methods of analysis;
electrochemical methods where current voltage curves obtained at the
surface of microelectrodes are studied.
In polarography the microelectrode is a dropping mercury
electrode (DME).
The method is used for the analysis of electroreducible or oxidizable
metal, ion or organic substance (electroactive species).
Electroactive species is transferred into a polarographic cell
(electrolytic cell) where voltage is applied to the electrodes
One of the electrodes is a polarizable microelectrode (DME) while the
other is reference non polarizable electrod
