Anodische zersetzung von amalgamen wenig in quecksilber löslicher metalle

Abstract

The amalgams of metals which are scarcely soluble in mercury, although the metal exists only as a suspension, can be smoothly anodically dissolved at high current densities without attack of the mercury. All the different amalgams show in a wide current density region the potential of the mercury dissolution reaction. Investigations on amalgams containing several components showed that in spite of the same dissolution potential the metals are not dissolved to the same extent. The metals are dissolved in the order, manganese, copper, iron, nickel, cobalt. Suggestions are made for a reaction path which explains the observations.
