ADSORPTIVE STRIPPING VOLTAMMETRIC DETERMINATION OF 1-(4-BROMOPHENYL)-3,3-DIMETHYLTRIAZENE

The optimum conditions were established for the determination of the g enotoxic substance 1-(4'-bromophenyl)-3,3-dimethyltriazene by differen tial-pulse voltammetry at a hanging mercury drop electrode in the conc entration range 1 x 10(-4) to 1 x 10(-7) mol dm(-3). The sensitivity o f the determination can be improved through adsorptive accumulation of the investigated substance on the surface of the hanging mercury drop electrode: differential pulse adsorptive stripping voltammetry can be used in the concentration range 1 x 10(-7) to 2 x 10(-10) mol dm(-3). The relative standard deviation (for ten determinations at 2 x 10(-10 ) mol dm(-3)) was 7.5%.
