The Influence of Various Factors on Electrochemical Reduction of the Bismuth Ions

Abstract

The electrochemical reduction of the bismuth ions has been investigated in the tartaric electrolyte. Kinetics and mechanism of the process and the effect of various factors on the electroreduction process of the bismuth ions have been studied according to cyclic and liner polarization curves drawn on the Pt electrodes. According to data, the value of effective activation energy has been calculated. The results of the calculation indicate that the electrochemical reduction process of the bismuth ions is accompanied by electrochemical polarization.

Electrochemical Behavior of Bismuth Ions in Ethylene Glycol

“…Compared with aqueous electrolytes in non-aqueous electrolytes, electroreduction occurs at more negative potentials, which is associated with the low conductivity of these electrolytes [16,18].…”

“…The author of [18] investigated the electrochemical reduction of bismuth ions from a water-tartaric acid electrolyte. By taking cyclic and linear polarization curves on Pt electrodes, we studied the kinetics, mechanism of process, and influence of various factors on the electroreduction of bismuth ions.…”

Electrochemical Behavior of Bismuth Ions in Citrate Solutions

“…The results show that the electroreduction process of bismuth ions from tartrate solutions at a potential range of 0.5 -(-0.35) V occurs in multiple stage. The dependence between i p and  1/2 indicates that the electroreduction process is accompanied by diffusion polarization [20,21].…”
