voltammetry1940

1940 Kolthoff & Laitinen in Science 16 Aug. 152/1 By the term ‘voltammetry’ we mean the determination and interpretation of current-voltage curves obtained in electrolysis experiments using a suitable microelectrode as an indicator electrode.

1978 Kirk-Othmer Encycl. Chem. Technol. (ed. 3) II. 618 Voltammetry is the general procedure of studying the current-voltage behavior of a microelectrode in a system which also contains a large nonpolarizable reference electrode and a large excess of an electrolyte... Polarography is a special case of voltammetry in which the small, polarizable electrode is a capillary tube from which small mercury droplets emerge at regular intervals... The plot of current vs voltage..provides qualitative and quantitative information about the solution composition.
