Polarographic and Voltammetric Determination of Genotoxic 9-Fluorenone Using Mercury and Silver Solid Amalgam Electrodes
Abstract
Polarographic and voltammetric behavior of genotoxic 9-fluorenone was investigated by DC tast polarography (DCTP) and differential pulse polarography (DPP), both at a dropping mercury electrode (DME), by differential pulse voltammetry (DPV) at a hanging mercury drop electrode (HMDE), and by DC voltammetry (DCV) and DPV at mercury meniscus modified silver solid amalgam electrode (m-AgSAE). The mechanism of electrochemical reduction of 9-fluorenone was also investigated.
Optimum conditions have been found for the determination of 9-fluorenone in buffered aqueous-methanolic solutions by the above mentioned methods in concentration ranges of 2×10–6 – 1×10–5 mol L–1 (DCTP at DME), 2×10–7 – 1×10–5 mol L–1 (DPP at DME), 2×10–8 – 1×10–5 mol L–1 (DPV at HMDE), 8×10–7 – 2×10–5 mol L–1 (DCV at m-AgSAE), and 8×10–7 – 4×10–5 mol L–1 (DPV at m-AgSAE).
