摘要：
The kinetics of cathode reactions occurring on a gold electrode in acidic thiourea-citrate electrolytes has been studied. Using classical electrochemical methods (potentiometry, chronovoltammetry, electrogravimetry) and graphic-analytical calculations, the following were established: the instability constant of gold complexes, the type of kinetics, the nature of the delayed stage, and the main kinetic characteristics of the electrochemical reaction during gold deposition.
