摘要: Abstract In an aqueous acid medium, 4,4′-bipyridine (BPH22+) may give up to five voltammetric reduction peaks, depending on its concentration and the presence or absence of a surfactant. This paper discusses such peaks assigns them electrode processes from which they originate. If scan is reversed when most negative potential in voltammogram reached, only three previously observed are reversible, final potential. Also, two inverted current (ie, peaks) positive potentials. Plausible mechanisms accounting for put forward paper.
