Abstract
Divalent silver halides provide a source for divalent bactericidal silver ions in the presence of persulfate. The halides are especially effective when applied to water used in industrial cooling installations, hot tubs and swimming pools and will conform to stringent EPA requirements for waters utilized for bathing as in tubs and pools of 100% kills of 100 K/cc E. Coli coliforms within 10 minutes, exemplary of which are the chloride and bromide which give 100% kills within 5 minutes. The halides, of course, can be used in salty water since they are solids immune from halide action that would otherwise precipitate soluble divalent silver from solution.
