Abstract
Divalent silver oxide provides a source for divalent bactericidal silver ions in the presence of persulfate. This oxide is especially effective when applied to water used in industrial cooling towers, hot tubs and swimming pools and conforms to stringent EPA requirements of 100% kills of 100K/cc Streptococcus faecalis within 10 minutes. The oxide also can be used in water with exceptionally high salt content without halide curdy precipitate formation and will not stain the skin of users who may inadvertently be exposed to it.
