Metallothionein (MT) yields on mercury electrodes a "presodium" catalysis of the evolution of hydrogen, which is, as a peak-shaped signal, particularly well measurable in chronopotentiometry, and which is, unlike presodium catalytic effects of other biopolymers, strongly dependent on the presence of cobalt ions in the solution. The behavior of the "presodium" derivative chronopotentiometric peak under various experimental conditions was tested.
