The polarographic reduction of the azodye semitrypane blue has been studied, a mechanism has been proposed and optimal conditions have been found for the determination of this substance by TAST polarography (to 2*10-6 mol*l-1) and differential pulse polarography (to 1*10-7 mol*l-1) at a classical dropping mercury electrode and by fast scan differential pulse voltammetry (to 1*10-8 mol*l-1) and linear scan voltammetry (to 1*10-8 mol*l-1) at a hanging mercury drop electrode.The detection limit was decreased to 1*10-9 mol*l-1 for fast scan differential pulse voltammetry and 1*10-10 mol*l-1 for linear scan voltammetry by using adsorptive accumulation of the determined substance at the hanging mercury drop electrode.

The reduction of mutagenic bisazodye trypane blue has been studied at a mercury electrode, a mechanism has been proposed and optimal conditions found for its analytical application.The use of a dropping mercury electrode with a renewable surface yielded a detection limit of 8*10-7 mol l-1 for TAST polarography, and 8*10-8 mol l-1 for differential pulse polarography; the use of a hanging mercury drop electrode with an unrenewed surface during the measurement yielded detection limit of 6*10-8 mol l-1 for fast scan differential pulse voltammetry and4*10-8 mol l-1 for linear scan voltammetry.Preliminary adsorptive accumulation of the determined substance on the surface of the hanging mercury drop electrode led to a decrease in the detection limit to 5*10-9 mol l-1 for linear scan voltammetry.
