Abstract

Voltammetric behavior of two genotoxic nitro compounds (2-amino-6- nitrobenzothiazole, ANBT, and 5-nitrobenzimidazole, 5-NBIA) has been investigated using direct current voltammetry (DCV) and differential pulse voltammetry (DPV) at a polished silver solid amalgam electrode modified by microcrystalline natural graphite-polystyrene composite transducer (shortly denoted as carbon film electrode - CFE). The optimum conditions have been found for their determination in the Britton-Robinson buffer solutions. The practical applicability of the newly developed methods was verified on model samples of drinking and river waters.
