EMBED (for The limiting current (the plateau on the sigmoid), called the diffusion current since diffusion is the most important contribution to the flux of electroactive material at that point of the Hg drop life, is linked to analyte concentration by the Ilkovic equation: ilkovic equation:- * When dropping mercury electrode (DME) is held in mass transfer controlled region of electrolysis current will be flowing during the light time of the single drop of Hg. This current know as diffusion limiting current. 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

Direct-current polarography dates back 80 years to the discovery by J. Heyrovsky that highly reproducible current-potential curves could be obtained using a dropping mercury electrode [1-3]. Faradaic and non-faradaic processes at this electrode have become soon an attractive field of research for many chemists, physicists, biologists, physicians, and environmental scientists.

Cottrell equation is a consequence of Fick’s laws of diffusion. 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 = / / / Polarographic wave equation, Dropping Mercury Electrode, Ilkovic, Cottrell, Ficks For lecture notes and practice questions visit:| christcollegevoc.com History of the Ilkovic equation.
