SPECTROFLUOROMETRIC HYDRODYNAMIC VOLTAMMETRY - THE INVESTIGATION OF ELECTRODE-REACTION MECHANISMS

Spectrofluorimetric hydrodynamic voltammetry (SFV) is used to study th e electroreduction of crystal violet in acetonitrile solution. The SFV technique is shown to have high sensitivity and to complement convent ional electrochemical experiments through its identification of leucoc rystal violet as an electrolysis product generated in low concentratio n in addition to the radical species formed as a one-electron adduct o f the parent compound and previously thought to be produced exclusivel y. Mechanistic SFV studies show that the leucocrystal violet is formed via an EC process for which kinetic parameters are reported.
