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]
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.
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.
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 ...
In electrochemistry, the Randles–Ševčík equation describes the effect of scan rate on the peak current (i p) for a cyclic voltammetry experiment. For simple redox events where the reaction is electrochemically reversible, and the products and reactants are both soluble, such as the ferrocene/ferrocenium couple, i p depends not only on the concentration and diffusional properties of the ...
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 ]
In his polarography practical book, titled Chemische Analysen mit dem Polargraphen, Hohn referred this method as Eizhusatzes, which translates to "calibration addition" in English. Later in the German literature, this method was called as Standardzugabe , meaning "standard addition" in English.
