摘要：
An apparatus for de-silvering a silver-containing solution, comprises a plurality of electrolysis cells (10, S1, S2) each having an anode (20, 120, 220) and a cathode (30, 130, 230). A master cell (10) further comprises a reference electrode (45). The remaining cell or cells constitute slave cells (S1, S2). Control means (41) adjust the cathode potential applied to the slave cells (S1, S2) in response to the current flow (I.sub.M) through the master cell (10). The apparatus is particularly suitable for de-silvering large volumes of silver-containing solution, without the use of high currents.
