Biocidal polymers (I): Preparation and biological activity of some novel biocidal polymers based on uramil and its azo-dyes
Local-affordable- access to safe drinking water sources is a major problem worldwide. Poor dosage of chemicals (such as bleach) involved in water purification in communities without appropriate infrastructure may become an unsuitable response. We developed N-halamine biocidal polymers as insoluble (safe), self-dosing, bleach-like releasing systems. Our design increased the biocidal capacity 2-4-fold per polymer weight compared with established structures, whilst increasing stability to inhibit release of halogen in the absence of contaminating biological matter. Water filters-based on this system are now being used to purify water at community level in Egypt.
