Zinc electrodeposition on copper substrate using cyanide bath for the production of 66,67,68Ga

The electroplating of zinc is carried out in an alkaline cyanide bath. Operating parameters such as pH, temperature, and current density and amount of the electrolyte components are optimized. The optimum conditions of the electrodeposition of zinc were as follows: 2.7 g L-1 ZnO, 7.1 g L-1 KCN, 11.1 g L-1 KOH, pH = 13-14, DC current density of ca 8.55 mA cm-2 at 40-50 deg C temperature with 89% current efficiency. SEM photomicrographs revealed fine-grained structure of the deposit from the bath. (author)
