Abstract
The optimum conditions were established for the determination of the genotoxic substance 1-(4′-bromophenyl)-3,3-dimethyltriazene by differential-pulse voltammetry at a hanging mercury drop electrode in the concentration range 1 × 10-4 to 1 × 10-7 mol dm-3. The sensitivity of 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 1x10-7 to 2 × 10-10 mol dm-3. The relative standard deviation (for ten determinations at 2 × 10-10 mol dm-3) was 7.5%.
