摘要

Electrode for the regeneration of chromic acid solutions has a porous structure through which a chromic acid solution can pass. An independent claim is also included for an electrolysis cell for the electrochemical oxidation of Cr3+> in a chromic acid solution comprising an anode made of the above electrode. Preferred Features: The porous structure is a fixed bed made of a particle charge. The particles are coated with a lead oxide layer.
