/ ˌpəʊləˈrɒɡrəfɪ; ˌpəʊlərəˈɡræfɪk /

noun

1. 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
