PROBLEM TO BE SOLVED: To produce electrolytic sulfuric acid solution using a sulfuric acid solution efficiently.SOLUTION: In a production method of an electrolytic sulfuric acid solution using a primary sulfuric acid solution of relatively low sulfuric acid concentration, and a secondary sulfuric acid solution of relatively high sulfuric acid concentration, a primary electrolytic sulfuric acid solution is produced by decomposing the primary sulfuric acid solution electrolytically, a secondary electrolytic sulfuric acid solution where the sulfuric acid concentration was adjusted to a predetermined concentration is produced by admixing the secondary sulfuric acid solution to the primary electrolytic sulfuric acid solution, and then the secondary electrolytic sulfuric acid solution is decomposed electrolytically while being circulated between the utilization side.SELECTED DRAWING: Figure 3 |
