Abstract

The polarographic behaviour of 2-nitronaphthalene was investigated by DC tast polarography (DCTP) and differential pulse polarography (DPP), both at a dropping mercury electrode, and differential pulse voltammetry and adsorptive stripping voltammetry, both at a hanging mercury drop electrode. Optimum conditions have been found for the determination of 2-nitronaphthalene by the given methods in the concentration ranges of 2×10-6- 1×10-4, 2×10-7-1×10-4, 1×10-8-1×10-4 and 2×10 -9-1×10-8 M, respectively. Practical applicability of these techniques was demonstrated by the determination of 2-nitronaphthalene in drinking and river water after its preliminary separation and preconcentration using liquid-liquid and solid-phase extraction with limits of determination of 3×10-10 M (drinking water) and 3×10 -9 M (river water).
