Process for recovering chromic acid solution from a waste liquor containing chromic ions |
| abstract |
From a chromate ion-containing aqueous waste liquor the chromate ion can be advantageously recovered in the form of chromic acid by the process comprising the steps of adding a reducing agent to the chromate ion-containing aqueous waste liquor to precipitate the chromate ion in the form of chromium (III) hydroxide; adding an alkali and aqueous hydrogen peroxide to the precipitated chromium (III) hydroxide to produce a chromate ion-containing aqueous solution; and passing the resultant chromate ion-containing aqueous solution through an H form acidic cation-exchange resin. |
