THE POLAROGRAPHIC AND VOLTAMMETRIC DETERMINATION OF 2-AMINO-5-SULPHOAMOYLNAPHTHALENE-AZO-(2'-CHLORO-4'-NITROBENZENE)

The polarographic reduction of the title azo dye was studied, a mechanism was suggested and optomal conditions were determined for analytical utilization of this process.A detection limit of 3*10-7 mol l-1 was obtained using fast scan differential pulse voltammetry and 0.7*10-7 mol l-1 using linear potential scan voltammetry at a hanging mercury drop electrode.The detection limit can be decreased by adsorptive accumulation of the determined substance on the surface of hanging mercury drop electrode, to 1*10-8 mol l-1 for fast scan differential pulse voltammetry and 0.6*10-8 mol l-1 for linear scan voltammetry.The selectivity of the determination can be improved by preliminary separation by extraction or thin-layer chromatography.
