Process for the preparation of chromic acid |
| abstract |
The invention relates to a process for the electrolytic production of chromic acid, in which ferrochrome is dissolved in sulfuric acid and the Cr is separated off as Cr alum and then the Cr (III) hydroxide is precipitated out of the Cr alum solution, dissolved again in a solution containing chromic acid and is processed electrolytically to chromic acid. |
