Method for treating iron-containing waste sulfuric acid |
| abstract |
The present invention relates to a method for treating heavy metal-containing spent sulfuric acid. To this end, the iron-containing spent sulfuric acid or the iron-containing sulfuric acid material obtained therefrom reacts with a substance containing iron chloride and optionally other metal chlorides to produce iron (II) sulfate. Waste sulfuric acid is preferably derived from titanium dioxide production. |
