Abstract

PURPOSE: To dissolve away residual lead dioxde effectively without damaging the base metal by dipping an electrode for electrolysis made by coating lead dioxide on the base metal into mixed solutions of acetic acid, hydrogen peroxide, and hydrosilicofluoric acid in regenerating said electrode.
CONSTITUTION: Lead dioxide is coated on the surface of a metallic substrate such as Ti which is highly conductive and corrosion resistant, and this is used for a long period of time as the anode for electrolysis of an acidic aqueous soln., etc. When the lead dioxide layer is consumed and/or dislodged, the electrode is regenerated. At this time, this electrode is immersed in an aqueous soln. consisting of 10W35wt% acetic acid, 5W20wt% hydrogen peroxide, and 1W20wt% hydrosilicofluoric acid or its salts such as K salt or Na salt. The lead dioxde remaining on the base metal is dissolved away completely in a short time without damaging the Ti used as the base metal, whereby the surface of the substrate is cleaned. A lead dioxide layer is newly formed on this surface, whereby the lead dioxide anode is regenerated.
