Method of treating residual acid |
| abstract |
A method of treating residual acid from production of chlorine dioxide is described. The method is charac-terised in that a compound containing iron is added to the residual acid to react therewith and form a product, which contains iron in trivalent form. As iron compound preferably ferrous sulphate is added, which under oxida-tion reacts with the residual acid to form ferric salt. Preferably sodium chlorate, sodium hypochlorite, hydrogen peroxide or an oxygen-containing gas is added as oxidant. |
