Application of a cyclic renewable silver amalgam liquid film electrode (R-AgLAFE) to study the electroreduction processes of Bi(III) ions in the presence of cysteine

Abstract

The cyclically refreshable liquid silver amalgam film silver based electrode (R-AgLAFE) to study of electrode processes under the “cap-pair” conditions was used. The catalytic effect of cysteine on the Bi(III) ions electroreduction processes has been demonstrated. The magnitude of the catalytic effect is related to the formation of the Bi(III) – Hg(SR)2 active complexes mediating electron transfer equilibrium
