The Ilkovic equation is a relation used in polarography relating the diffusion current (I d) and the concentration of the depolarizer (c), which is the substance reduced or oxidized at the dropping mercury electrode. The Ilkovic equation has the form = / / / where:
Dropping mercury electrode. The dropping mercury electrode (DME) is a working electrode made of mercury and used in polarography.Experiments run with mercury electrodes are referred to as forms of polarography even if the experiments are identical or very similar to a corresponding voltammetry experiment which uses solid working electrodes.
Along with Nobel laureate Jaroslav Heyrovský, he helped to establish theoretical basis of polarography. In this field, he is the author of an important result, the Ilkovic's equation. He was also one of the leading figures in modern university-level physics education in Slovakia. [1]
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.
Differential pulse voltammetry (DPV) (also differential pulse polarography, DPP) is a voltammetry method used to make electrochemical measurements and a derivative of linear sweep voltammetry or staircase voltammetry, with a series of regular voltage pulses superimposed on the potential linear sweep or stairsteps.
These measuring techniques include: classical DC polarography, oscillopolarography, Kaloussek's switcher, AC polarography, tast polarography, normal pulse polarography, differential pulse polarography, square-wave voltammetry, cyclic voltammetry, anodic stripping voltammetry, convolution techniques, and elimination methods.

Workplace with Polarograph on the left. A Polarograph is a chemical analysis instrument used to record automatic voltage-intensity curves.. The Polarograph uses an electrolytic cell consisting of an electrode or microelectrode small area, generally of the mercury drop type, which is a very fine capillary tube through which mercury flows slowly, which comes in the form of small droplets, which ...
