Strehlow4, and Koutecky5 subsequently modified the Ilkovic equation to allow for the fact that diffusion takes place, not linearly, but towards a curved surface. The theory of polarography has now been developed in considerable detail, and accounts of it can be found in several textbooks, monographs, and handbooks6" The. According to Ilkovic equation(Id= X n X D1/2 X m2/3 X t 1/6 X C), the diffusion current (= limiting current - residual current) is directly proportional to the concentration of the electro-active material in the solution. If some of the electro-active material is removed by interaction. PRINCIPLE OF POLAROGRAPHY: PRINCIPLE OF POLAROGRAPHY 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.
