Polarography - Wikipedia
Polarography is an electrochemical voltammetric technique that employs (dropping or static) mercury drop as a working electrode. In its most simple form polarography can be used to determine concentrations of electroactive species in liquids by measuring their mass-transport limiting currents .

2024年1月24日 · The first important voltammetric technique to be developed—polarography—uses the dropping mercury (DME) electrode as the working electrode (see Figure 25.2.2 for a schematic diagram of the DME as well as two other types of Hg electrodes). In polarography, as in linear sweep voltammetry, …

2023年5月13日 · Polarography is a voltammetric technique that involves the oxidation (loss of electrons) or reduction (gain of electrons) of chemical species (ions or molecules) at the surface of a dropping mercury electrode (DME) at an applied potential.
Polarography | Electrochemical Analysis, Voltammetry
Polarography, in analytic chemistry, an electrochemical method of analyzing solutions of reducible or oxidizable substances. It was invented by a Czech chemist, Jaroslav Heyrovský, in 1922. In general, polarography is a technique in which the electric potential (or voltage) is …
Polarography - an overview | ScienceDirect Topics
Polarography is a voltammetric technique in which chemical species (ions or molecules) undergo oxidation (lose electrons) or reduction (gain electrons) at the surface of a dropping mercury electrode (DME) at an applied potential. Polarography only applies to the DME.
Electrochemistry Encyclopedia -- Polarography) - Electrochemical …
Simple principle of polarography is the study of solutions or of electrode processes by means of electrolysis with two electrodes, one polarizable and one unpolarizable, the former formed by mercury regularly dropping from a capillary tube.
Polarography - SpringerLink
Polarography, one of the most widespread electrochemical techniques both for the study of electrochemical processes and for analytical applications, was introduced in 1922 by Heyrovský.
Definition: Polarography is an electrochemical method of analysis based on the measurement of current flow resulting from the electrolysis of a solution at a polarisable microelectrode as a function of applied voltage.
