Ilkovic equation is a relation used in polarography relating the diffusion current (id) 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 id = k n D1/3m2/3t1/6c
5 Polarographic measurements are governed by ilkovic equation Ilkovic Equation — The linear relationship between the diffusion current (id) and the concentration of electroactive species is shown by the Ilkovic equation: id = 607 nCD1/2m2/3t1/6, id = diffusion current in microamperes; n = number of electrons required per molecule of electroactive Substance, D = diffusion coefficient, in square cm per second, C = concentration, in millimoles per L, m = mass of mercury flow from the DME, in
hy, one can verify ilkovic equation by measuring the effect of concentration on diffusion current using cyclic voltammetry. usually keeping all other parametets constant increasing concentration
The Ilkovic equation for the limiting diffusion current obtained with a dropping mercury electrode predicts that the instantaneous current grows during the life of the mercury drop as the one-sixth power of the time, and that the ratio of the instantaneous current at the end of the drop life (the maximum current) to the average current is 1.17. McKenzie (1948) showed in a preliminary study
2021-04-04 · Ilkovic equation Source: A Dictionary of Chemistry Author(s): John DaintithJohn Daintith. A relation used in polarography relating the diffusion current i a and the concentration c. The Ilkovic equation has
This equation shows that it decreases with time due to a broadening of the diffusion layer and a decrease in the diffusion rate. Noteworthy that this equation is the backbone of the Ilkovic equation.

This relation is the foundation of quantitative polarographic analysis and its general validity is well established. The results of polarographic Polarography is a voltammetric measurement whose response is determined by only diffusion mass transport. The 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. c.
