This study investigates the electrochemical stability of the gold complex based on mercaptotriazole at an optimum pH of nine in the electrolyte with a gold concentration of 2.5 g dm(-3). The stability of the complex was studied by visual monitoring and electrochemical characterization of electrolytes over a period of 1 year. Electrochemical characterization of the mercaptotriazole gold complex was performed using open circuit potential measurement, cyclic voltammetry, recording the polarization curves, pH, and conductivity of the electrolyte. Electrochemical characteristics and visual appearance of the mercaptotriazole gold complex at a pH similar to 9 were not significantly changed for one year, with no changes in its visual appearance. The results of this study are important for industrial applications in order to replace cyanide electrolytes with a stable organic complex.
