ELECTROCHEMICAL BEHAVIOR OF BISMUTH IONS IN CITRATE SOLUTIONS

Abstract

The scientific paper is devoted to the electrochemical reduction of bismuth ions from citrate electrolytes. The kinetics and mechanism of the process and the influence of various factors on the electroreduction process of bismuth ions were studied by recording cyclic and linear polarization curves on Pt, Ni and Ni/Bi electrodes. The effective activation energy and diffusion coefficient were calculated according to the obtained data. The results of the calculation show that the electroreduction process of the bismuth ions from citrate solutions is accompanied by diffusion polarization
