Abstract

Three different types of solid electrodes, namely silver electrode, silver composite electrode containing 20% (m/m) of silver powder, 20% (m/m) of graphite powder and 60% (m/m) of methacrylate resin and graphite composite electrode containing 30% (m/m) of graphite powder and 70% (m/m) of epoxy resin were tested for differential pulse voltammetric determination of selected genotoxic nitro-compounds using 2-nitronaphthalene, 6-nitroquinoline, and 5-nitrobenzimidazole as model compounds. It was found that all three electrodes can be used for the determination of micromolar concentrations of tested model substances, the limit of detection and other figures of merits being dependent both on the electrode used and the substance to be determined.
