Polarographic and Voltammetric Study of Genotoxic 2,7-Dinitrofluoren-9-one and Its Determination Using Mercury Electrodes

Abstract

Electrochemical behavior of genotoxic 2,7-dinitrofluoren-9-one was investigated by DC polarography and DC tast polarography, both at a dropping mercury electrode, and by cyclic voltammetry at a hanging mercury drop electrode, in buffered aqueous-methanolic solutions. The number of exchanged electrons was determined by constant-potential coulometry at a mercury pool electrode.

A possible mechanism of the electrochemical reduction has been proposed.
