Determination of Stevioside by Square-wave Voltammetry

2010
Steviol glycosides are electroactive compounds and can be detected by mercury electrode. The maxima of square-wave voltammograms of steviol and stevioside appear at -1.3 V vs Ag/AgCl in 1 M NaCl at approximately pH 11. The responses are quasireversible and probably caused by electro-reduction of carboxyl, or ester groups, respectively.

Measurement of the kinetics of adsorbed cinnoline by square-wave voltammetry

Analytical and Bioanalytical Chemistry, 2002
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.

Theory and application of square-wave voltammetry

2007
Square-wave voltammetry is one of the most sensitive voltammetric techniques provided by modern computer-controlled electrochemical instruments. It was developed by combining the high-amplitude, high-frequency square-wave with the fast staircase waveform. It can be used for both electrokinetic and electroanalytical measurements.

Determination of Probucol by Square-Wave Voltammetry

1999
A square-wave voltammetric method is developed for the determination of probucol on mercury electrode. Probucol is an important drug and it is a surface-active compound having tendency to adsorb on the surface of lipophilic mercury electrode. In neutral media, probucol shows electrochemical activity with SWV peak appearing at potential about -1.0 V. In
