Potential sweep chronoamperometry in dimethyl sulfoxide at the hanging mercury drop electrode

Abstract

Electroanalytical studies in dimethyl sulfoxide have been extended to the hanging mercury drop electrode. Potential sweep chronoamperometry was utilized with potentiostatic control of the working electrode. Several ions have been examined for diffusion control in this system by means of the Randies-Sevčik equation. Halfwave potentials of selected depolarizers and polarization limits of several carrier electrolytes have been measured.
