摘要

PROBLEM TO BE SOLVED: To provide a production method for inexpensively producing a silver-ion antibacterial liquid capable of immediately sterilizing a bacterium and including a silver citrate complex similar to TINOSAN SDC(R) as goods on the market, using silver zeolite that has a low raw material cost and a high degree of safety.SOLUTION: The method for producing a silver-ion antibacterial liquid is characterized in comprising: a process for weighing out A-type or X-type silver zeolite in a compounding amount of 0.1 to 20.0 wt.%, weighing out a compounding amount of citric acid in a compounding ratio of 1.2 or higher in relation to the silver zeolite, and compounding the silver zeolite and citric acid with purified water; a process for stirring and mixing the silver zeolite and citric acid compounded with the purified water; preparing a mixture liquid including at least a silver citrate complex and a silica hydrate; and a process for removing the silica hydrate formed in the mixture liquid.
