British Dictionary definitions for polarography

polarography

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. Because the cathode is small, polarization occurs and each type of anion is discharged at a different potential. The apparatus (polarograph) usually employs a dropping-mercury cathode
