Abstract

Abstract The polarographic reduction of the title azo dye was studied, a mechanism was suggested and optimal conditions were determined for analytical utilization of this process. A detection limit of 3. 10-7 mol 1-1 was obtained using fast scan differential pulse voltammetry and 0.7. 10-7 mol 1-1 using linear potential scan voltammetry at a hanging mercury drop electrode. The detection limit can be decreased by adsorptive accumulation of the ...
