THE REDUCTION OF FLUORESCEIN IN AQUEOUS-SOLUTION (AT PH-6) - A NEW DISP2 REACTION

It is shown using linear sweep and rotating-disc voltammetry that the reduction of the dye fluorescein at ca. pH 6 in aqueous solution proceeds via a DISP2 mechanism. In particular the rotating-disc measurements show voltammetric waves which display a shift in the half-wave potential with disc rotat...

Zusammenfassung:It is shown using linear sweep and rotating-disc voltammetry that the reduction of the dye fluorescein at ca. pH 6 in aqueous solution proceeds via a DISP2 mechanism. In particular the rotating-disc measurements show voltammetric waves which display a shift in the half-wave potential with disc rotation speed and which also analyse to give curved Tafel plots entirely in agreement with the behaviour predicted theoretically for a DISP2 process on the basis of a reaction layer treatment.
