ARSENIC-CONTAINING SOLUTION TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an arsenic-containing solution treatment method which can inhibit generation of a precipitate of arsenic compounds, which has low stability as an arsenic compound and is difficult to be separated from an arsenic-containing solution containing other elements including iron because of small particle diameter thereof.

SOLUTION: In the arsenic-containing solution treatment method, an oxidizing agent is added to the acidic arsenic-containing solution which contains pentavalent arsenic and trivalent iron, and is under the atmospheric pressure.
