Quantitative Anodic Chronopotentiometry at Platinum Electrode

Organic Polarography

“…The effect of p H on the reduction of aromatic hydrocarbons (666) is similar to that observed when water is added to solutions of the hydrocarbons in dimethylformamide.…”

“…The oxidation product from anthracene was the anthryl ion (XXXIII) and has been isolated in a large-scale oxidation H I H XXXIII N XXXIV in the presence of pyridine as the dipyridinium salt (XXxrV) (386). This oxidation of anthracene was verified by the chronopotentiometric technique (666).…”

Effect of Electrode Configuration and Transition Time in Solid Electrode Chronopotentiometry

“…Several papers recommend choosing the current density to obtain short transition times (0.3 to 1 second) (10, 19), while other authors prefer transition times in the range of 10 to 60 seconds (3,14,18). Chronopotentiometry with solid electrodes also allows the choice of an electrode from a number of different types that have been used, which include: disk electrodes (platinum disk embedded in glass) (3,9,10,20), foil electrodes (9,10,14,18,20), cylindrical wire electrodes (9, 10, 19, 20), and wire loop electrodes (20). This paper discusses factors which affect choice of electrode and transition time range.…”
