Abstract:
1. A method of preparing a silver loaded activated carbon fiber comprising the steps of: (1) treating a viscose fiber with a hydroxyalkyl cyclodextrin aqueous solution to obtain a hydroxyalkyl cyclodextrin loaded viscose fiber, (2) treating the hydroxyalkyl cyclodextrin loaded viscose fiber with a silver salt aqueous solution to obtain a hydroxyalkyl cyclodextrin and silver salt loaded viscose fiber, (3) heating the hydroxyalkylated cyclodextrin and silver salt loaded viscose fiber in deionized water at 80 to 100° C. to obtain a silver loaded viscose fiber, (4) treating the silver loaded viscose fiber with a disodium hydrogen phosphate aqueous solution and then heating the treated silver loaded viscose fiber under nitrogen at 400 to 600° C. to obtain a silver loaded carbon fiber, and (5) heating the silver loaded carbon fiber under nitrogen and water vapor at 900 to 1,200° C. to obtain the silver loaded activated carbon fiber.
