Voltammetric behavior of selected genotoxic nitro compounds (2-nitrofluorene, 2,7-dinitrofluorene, 2-nitro-9-fluorenone and 2,7-dinitro-9-fluorenone) has been investigated using direct current voltammetry (DCV), differential pulse voltammetry (DPV) and adsorptive stripping differential pulse voltammetry (AdSDPV) at a mercury meniscus modified silver solid amalgam electrode (m-AgSAE). The optimum conditions have been found for their determination in a 1 : 1 mixture of methanol and aqueous Britton–Robinson buffer solution, with the limits of quantification, (LOQ), 2, 0.3, 0.5, and 0.5 μmol L−1 (DCV at m-AgSAE) and 0.2, 0.2, 0.4, and 0.2 μmol L−1 (DPV at m-AgSAE) for 2-nitrofluorene, 2,7-dinitrofluorene, 2-nitro-9-fluorenone, and 2,7-dinitro-9-fluorenone, respectively. An attempt at increasing the sensitivity using AdSDPV at m-AgSAE was successful only for 2-nitrofluorene (LOQ=2 nmol L−1).
