Cyclic Voltammetric Study of High Speed Silver Electrodeposition and Dissolution in Low Cyanide Solutions

Figure 1

Cyclic voltammograms of (a) silver electrodeposition and silver dissolution in the absence and presence of KNO₃ and KCN; (b) 120 g/L KAg(CN)₂ only; (c) the influence of cathodic vertex potential in 120 g/L KAg(CN)₂, 6 g/L KCN, and 120 g/L KNO₃ solutions. Arrows show the potential sweep direction. Initial potential = +0.6 V. Sweep rate: 50 mVs⁻¹. C1, C2, and C3 denote the cathodic peaks while A1 and A2 correspond to the anodic peaks.
