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:
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]
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.
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.
Linear potential sweep. In analytical chemistry, linear sweep voltammetry is a method of voltammetry where the current at a working electrode is measured while the potential between the working electrode and a reference electrode is swept linearly in time.
In electrochemistry, the Cottrell equation describes the change in electric current with respect to time in a controlled potential experiment, such as chronoamperometry. Specifically it describes the current response when the potential is a step function in time.
Staircase potential sweep (black) set against a linear potential sweep (blue) Comparison of the current response of a platinum disc electrode in 1 M sulphuric acid given by linear sweep voltammetry and staircase voltammetry methods.
Image explaining the origins of the potential waveform in squarewave voltammetric analysis. Squarewave voltammetry (SWV) is a form of linear potential sweep voltammetry that uses a combined square wave and staircase potential applied to a stationary electrode. [1]
