Polarography:Working and Application

Polarography Seminar Report

Polarography is the study of the electrolysis of solutions of electrooxidizable and electroreducible substances between a dropping mercury electrode (DME) and some reference electrode (RE) . The potential between these electrodes is varied and the consequent changes in the flow of current is measured.On plotting the changes in current flow versus the potential variation, one obtains an i - E curve known as polarogram. The first scientist who discovered the use of the DME in electrolysis is Jaroslave Heyrovsky in 1922 and received the Nobel Prize in Chemistry in 1959.
