Silver ion antibacterial liquid production method, silver ion antibacterial liquid produced by the method, or silver ion antibacterial powder production method, silver ion antibacterial powder produced by the method
The present invention, whose object is to provide a production method that can produce at low cost a silver-ion antibacterial liquid offering immediate bactericidal effect, by using a silver zeolite being a low-cost material and offering characteristics that ensure high safety, is characterized in that the silver zeolite is a type A or type X silver zeolite, and that the method comprises: a process to weigh the silver zeolite and obtain a blending quantity of it in a range of 0.1 to 20.0 percent by weight and then weigh the citric acid and obtain a blending quantity of it so that its blending ratio to the silver zeolite becomes 1.2 or greater, followed by blending of the two into purified water； a process to mix under agitation the silver zeolite and citric acid blended in the purified water to prepare a mixture liquid containing at least a citric acid-silver complex and silica hydrate； and a process to remove the silica hydrate produced in the mixture liquid.
