Abstract — The anodic behavior of silver in aqueous and water–glycerol solutions of potassium thiocyanate is studied on motionless and rotating-disk electrode. The appearance of the limiting current is explained. Optimal solution compositions and conditions for the process (which ensure metal polishing) are suggested.
