A method for producing a microbubble-containing electrolyte solution and a method for producing a microbubble-containing solvent used for preparing a microbubble-containing electrolyte solution.
PROBLEM TO BE SOLVED: To provide a method for producing an electrolyte solution which can contain high-concentration microbubbles by suppressing the reduction of microbubbles during filtration, and a method for producing a microbubble-containing solvent which can be used for preparing the electrolyte solution. To do. A method for producing a microbubble-containing electrolyte solution includes a filtration step of filtering a microbubble-containing solvent with a filter medium and a preparation step of preparing an electrolyte solution from the obtained filtrate, and the cation in the microbubble-containing solvent. The ion concentration is less than 20 mmol / L and satisfies at least one of the following conditions (1), (2), and (3). Condition (1): The density of microbubbles in the microbubble-containing solvent is 1 × 106 cells / mL or more. Condition (2): A solvent preparation step of introducing microbubbles into a solvent to prepare a microbubble-containing solvent is included. Condition (3): The density of microbubbles in the electrolyte solution is 1 × 105 cells / mL or more.
