British Dictionary definitions for polarography
polarography
/ (ˌpəʊləˈrɒɡrəfɪ) /
noun
a technique for analysing and studying ions in solution by using an electrolytic cell with a very small cathode and obtaining a graph (polarogram) of the current against the potential to determine the concentration and nature of the ions.
