Polarographic studies with dropping amalgam electrodes.

The polarographlc method of chemical analysis was Introduced by Professor J. Heyrovsky in a series of papers published between 1922 and 1926. The method is based on interpretation of the currentpotential curves obtained when electro-reducible or electro-oxidlzable substances are reduced or oxidized at a dropping mercury electrode. The complete electrolytic cell usually consists of a dropping mercury electrode, an electrolyte and a quiet pool of mercury in the bottom of the cell which acts as the other electrode. [...
