METHOD FOR PRODUCING SILVER-ION ANTIBACTERIAL LIQUID, SILVER-ION ANTIBATERIAL LIQUID PRODUCED BY SAID METHOD, METHOD FOR PRODUCING SILVER-ION ANTIBATERIAL POWDER, AND SILVER-ION ANTIBATERIAL POWDER PRODUCED BY SAID METHOD
A method for producing silver-ion antibacterial liquid using a type A or type X silver zeolite includes a process to weigh silver zeolite for obtain its blending quantity in a range of 0.1 to 20.0 percent by weight and to weigh citric acid for obtaining its blending quantity such 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. The production method can produce at low cost a silver-ion antibacterial liquid offering immediate bactericidal effect.
