4. Polarography
 Polarography is one of the Voltametric methods of
analysis; electrochemical methods where current voltage
curves obtained at the surface of microelectrodes are
studied.
 The method is used for the analysis of electroreducible
or oxidizable metal, ion or organic substance
(electroactive species).

6. Principle
 Principle of polarography is based on polarization action
on indicator electrode due to mercury and analyte in
solution.
