1. A process for electro-chemical oxidation regeneration of residual, organic material-contaminated sulfuric acids, characterized by combining successively, in this order, a reduced pressure concentration at a temperature lower than or equal to 155 degrees C until obtaining an acid of a sulfuric acid titre by weight of between 75 and 85% and, then, an electro-chemical oxidation in an electrolyzer without diaphragm, carried out at a temperature of between 70 and 90 degrees C. |
