Abstract

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