Abstract

Optimal conditions were found for the determination of 6-nitrobenzimidazole by tast polarography (at 1 × 10<sup>–4</sup>–1 × 10<sup>–6</sup> mol l<sup>–1</sup>), by differential pulse polarography at dropping mercury electrode (at 1 × 10<sup>–4</sup>–1 × 10<sup>–7</sup> mol l<sup>–1</sup>), and by differential pulse voltammetry at hanging mercury drop electrode (at 1 × 10<sup>–4</sup>–1 × 10<sup>–8</sup> mol l<sup>–1</sup>). Practical applicability of the developed methods was verified on the determination of 6-nitrobenzimidazole in drinking water (at 10<sup>–8</sup> mol l<sup>–1</sup>). Coulometry at constant potential and cyclic voltammetry were used for elucidation of the mechanism of electrochemical reduction.
