PROCESS FOR PREPARING ALKALIDICHROMATE AND CHROMIUM ACID |
| abstract |
The invention relates to a process for the preparation of Alkalidichromaten and chromic acid by electrolysis of Alkalimonochromat- or Alkalidichromatloesungen. According to the invention, dimensionally stable anodes of valve metals are used, which are activated by electrodeposition of noble metals and / or noble metal compounds from melts containing noble metal salts. According to the invention, the anodes are activated with platinum, iridium, with platinum and iridium compounds or alloys of said elements and compounds {alkali-monochromate; alkali metal dichromate; Electrolysis; dimensionally stable anodes; activated valve metals; precious metals; Precious metal compounds} |
