The applicability of differential pulse voltammetry (DPV) and adsorptivestripping voltammetry (AdSV) at a non-toxic meniscus-modified silver solid amalgamelectrode (m-AgSAE) for the determination of trace amounts of genotoxic substances wasdemonstrated on the determination of micromolar and submicromolar concentrations of3-nitrofluoranthene using methanol - 0.01 mol L-1 NaOH (9:1) mixture as a base electrolyteand of Ostazine Orange using 0.01 mol L-1 NaOH as a base electrolyte.
