Abstract

Voltammetric behavior of the genotoxic environmental pollutant 2-aminofluoren-9-one (2-AFN) was 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). Optimum conditions were found for its DCV and DPV determination in a methanol-Britton-Robinson buffer pH4.0 (1:9, v/v) medium (in a concentration range from 0.1 to 100μmolL-1 of 2-AFN) and for its AdSDPV determination in a 0.2molL-1 acetate buffer pH4.0 medium (from 0.01 to 0.1μmolL-1 of 2-AFN), with limits of quantification (LQs) of 0.2, 0.1 and 0.005μmolL-1 for DCV, DPV and AdSDPV, respectively. For comparison, the UV spectrophotometric (measured at 274nm) and fluorimetric (measured at 460nm, using the excitation wavelength of 314nm) determination of 2-AFN were carried out in methanol, with LQs of 0.1 and 2μmolL-1, respectively. Practical applicability of the newly developed voltammetric methods was verified on direct determination of 2-AFN in model samples of drinking and river water, with the lowest LQs in the range of 5-10nmolL-1.
