ANTIMICROBIAL SYNTHETIC ION EXCHANGE RESINS

摘要

A method of preventing the growth of heterotrophic bacteria and the subsequent establishment of a biofilm on the surface and in the micropores of an antimicrobial synthetic ion exchange resin. An antimicrobial synthetic ion exchange resin that prevents the growth of heterotrophic bacteria and the subsequent establishment of biofilm on the surface and in the micropores of the resin. A broad spectrum organic antimicrobial agent that is water insoluble and thus precipitates out and becomes encapsulated within micropores of the resin during suspension polymerization. The antimicrobial agent is submicron sized and has a high surface area. The antimicrobial agent protects the antimicrobial synthetic ion exchange bead from the growth of heterotrophic bacteria and the subsequent establishment of biofilm on the surface and in the micropores of the resin. The antimicrobial agent is nontoxic, noncarcinogenic, substantially nonleaching and durable over the lifespan of the bead.
