Measurement of the kinetics of adsorbed cinnoline by square-wave voltammetry.
The standard redox reaction rate constant of cinnoline (1,2-benzodiazine) adsorbed to the mercury electrode in 0.9 mol L(-1) KNO(3) buffered to pH 7, 9.2, and 4.65 are k(s)=455+/-110 s(-1), 65+/-25 s(-1), and 300+/-75 s(-1), respectively.
