摘要：
Recovery of Ag from AgCl by its direct reduction was investigated in the cell Zn\H2SO4, AgCl\Ag, where AgCl did not directly contact with the reducing metal. Observed sudden drop of the current and of the Ag\AgCl electrode potential indicated the end of the reduction process. An equation describing dependence of the current intensity in the cell Zn\H2SO4, AgCl\Ag on reduced time was derived and discussed. Current efficiency and reduction degree were also determined. Influence of the concentration of sulfuric acid on the rate of the process and on the size of the reduced silver grains was studied.
