Method for separating arsenic and antimony in arsenic acid aqueous solution |
| abstract |
Provided is a method for efficiently separating arsenic and antimony from an arsenic acid aqueous solution containing antimony at a concentration of 1.0 g / L or more. SOLUTION: A sulfur dioxide gas is blown into an arsenic acid aqueous solution containing antimony, arsenic and antimony are reduced, and a precipitate containing arsenous acid (As 2 O 3 ) and diantimony trioxide (Sb 2 O 3 ). Step (A) for obtaining a product 4, and adding the precipitate to warm water having a temperature of 70 to 100 ° C., dissolving arsenous acid in the precipitate, and containing an arsenous acid aqueous solution 8 and antimony A step (B) of obtaining an undissolved residue.
