The objective of this work was to investigate the stability of the gold complex based on
mercaptotriazole in slightly acid media, at pH=4. The gold complex complex was studied by the visual monitoring and electrochemical characterization of electrolytes in the period of three months.
Electrochemical characterization was performed by the open circuit potential measurement, cycling
voltammetry method and recording the polarization curves, with pH of the electrolyte measurement
before and after each electrochemical experiment. These tests, performed at pH=4 and optimal
concentration of gold in the electrolyte of 2.5 g/dm3, for a period three months, did not show any visual or other essential changes of investigated electrolyte characteristics.
