The kinetics and mechanism of the chemical dissolution of sil-ver in thiocarbamide solutions with an oxidant (FeIII) and electroreduction from a two-layer water–organic system under hydrodynamic electrolysis conditions (120 rpm) to obtain spheroidal nanosize silver particles are investigated. The kinetic laws governing the process of anodic dissolution of gold in acid thiocarbamide solutions to fabricate electrolytes for gold deposition are studied; the kinetic parameters of the process are calculated, and its mechanism is described. Spheroidal nanoscale gold and silver cathode deposits are obtained. The topography of the gold and silver cathode deposits obtained is studied by scanning electron microscopy, and their nanostructure is confirmed. To produce nanostructured gold and silver cathode deposits on an industrial scale, a design of electrolyser for work with two-layer water–organic electrolytes is developed.
