Polarography - Wikipedia
Polarography is an electrochemical voltammetric technique that employs (dropping or static) mercury drop as a working electrode. In its most simple form polarography can be used to …
Notes on Polarographic Principles and Instrumentations
Polarography is based on applying a progressively rising voltage between two electrodes. One of these voltages is polarisable (dropping mercury electrodes) and the other non-polarisable, …
