6. A method for preparing an inorganic antibacterial agent containing high-valence silver, comprising the following steps:
-
adding a solid carrier, which is capable of ion exchange, into a solution containing high-valence silver;
substantially stirring said solution to obtain a pulp formed solution for enabling an ion exchange reaction between said high-valence silver ion and the exchangeable ion of said solid carrier to yield a solid compound, and filtering and drying said solid compound to ultimately obtain said inorganic antibacterial agent containing high valence silver. - View Dependent Claims (7, 8, 9, 10, 11, 12)
