- 中文摘要: Anodic dissolution of gold in concentrated potassium cyanide solution was studied. Four regions of passivation were observed, each at —0.6V, +0.1V, +0.4V and +0.7V with respect to saturated calomel electrode. The passive phenomena were explained in terms of interaction of hydroxyl ions with gold surface. Oxygen effect on polarization was also discussed.
