Abstract
A sliver reduction process was studied in a low-cyanide-concentration solut ion in which the predominant species is the ion Ag(CN);. The electrochemica l behavior showed the presence of adsorbed electroactive species on the ele ctrode surface and this mas corroborated with the aid of an electrochemical quartz crystal microbalance (EQCM). The adsorption process is slow at open circuit and under this condition a simultaneous electroless deposition of silver nas detected with the EQCM.
