| titleOfInvention | Method for producing sulfuric acid solution |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a sulfuric acid solution which dissolves a metal with high efficiency at a high anode current density while suppressing passivation. SOLUTION: A method for producing a sulfuric acid solution includes an initial electrolytic cell supply step of supplying a sulfuric acid solution as an initial electrolytic cell to an electrolytic cell 10 in which the inside of the tank is divided into an anode chamber 21 and a cathode chamber 22 by a diaphragm, and an electrolytic cell. An electrolytic solution taking-out step of supplying a current to the anode-side electrode 13 and the cathode-side electrode 14 provided in the anode 10 and taking out the metal-dissolved electrolytic solution in which the metal constituting the anode-side electrode 13 is dissolved from the anode chamber 21. Is configured to include. Then, the supplied current reverses the direction in which it flows periodically. With this configuration, it is possible to suppress the movement of the metal melted on the anode side electrode 13 side to the cathode side electrode 14, and also to suppress the formation of passivation on the anode side electrode 13, so that the metal is efficiently high in quality. It is possible to produce a sulfuric acid solution in which is dissolved. [Selection diagram] Fig. 1 |
