Abstract

[PROBLEMS] To provide a method of recovering a high-purity acid from a nitric/hydrofluoric acid waste liquid through a small number of steps. [MEANS FOR SOLVING PROBLEMS] A pair of anion-exchange membranes (A) are disposed between an anode and a cathode. A cation-exchange membrane (C) and a monovalent-selective cation-exchange membrane (CIMS) are disposed in this order from the anode side between the pair of anion-exchange membranes (A). Electrodialysis is conducted while supplying a nitric/hydrofluoric acid waste liquid to a desalting deacidifying chamber (5) formed between one of the anion-exchange membranes (A) and the cation-exchange membrane (C) and further supplying an aqueous acid solution to a waste liquid chamber (7) which adjoins the desalting deacidifying chamber (5) and is formed between the cation-exchange membrane (C) and the monovalent-selective cation-exchange membrane (SC). Thus, nitric acid and/or hydrofluoric acid is recovered from an acid chamber (9) which adjoins the desalting deacidifying chamber (5) and is formed between a monovalent-selective cation-exchange membrane (SC) and the other anion-exchange membrane (A).
