| titleOfInvention | Method for producing pentavalent arsenic-containing liquid |
| abstract | A method for producing a pentavalent arsenic-containing liquid as a technology that makes it possible to combine the technology of “arsenic leaching of arsenic” with great industrial merit and the technology of “iron arsenic reaction in a low pH range” provide. In an aqueous solution in which trivalent arsenic is dissolved and the iron content is 1 g / L or less, an acid such as sulfuric acid is used with manganese dioxide (MnO 2 ) or lead dioxide (PbO 2 ) as an oxidizing agent. A process for producing a pentavalent arsenic-containing liquid in which the oxidation reaction of arsenic proceeds while the pH is maintained at 2 or less. The amount of the oxidizing agent present in the liquid is desirably 1 equivalent or more with respect to trivalent arsenic existing in the liquid before the arsenic oxidation reaction proceeds. Here, 2 mol of the oxidizing agent is defined as 1 equivalent per 1 mol of trivalent arsenic. [Selection] Figure 1 |
