PROBLEM TO BE SOLVED: To provide a method for producing an intraperitoneal lavage solution, which controls an active chemical species irradiated to an aqueous solution. The manufacturing method includes a plasma irradiation step of irradiating an aqueous solution containing L-sodium lactate with plasma. In the plasma irradiation step, a mixed gas containing nitrogen gas and oxygen gas is used as the plasma gas. The volume ratio of oxygen gas to nitrogen gas is 50% or more and 150% or less. Ar gas is supplied into the chamber 120 from the gas supply port 122 of the plasma processing apparatus 100. [Selection diagram] Figure 1 |
