*WARNING: Reagents marked with a * are considered hazardous substances. Material Safety Data Sheets (MSDS) are supplied for
these reagents. For your safety, read label and accompanying MSDS before using.
Ozone is sometimes used in place of, or in conjunction with, chlorine or other halogens for disinfection of pool, spa, or
drinking waters. Recently, large aquatic facilities have begun using ozone as a disinfectant in many artificial habitats.
APPLICATION: Drinking, pool and aquatic waters.
RANGE: 0.0 – 0.4 ppm Ozone
METHOD: Ozone rapidly and stoichiometrically decolorizes Indigo Trisulfonate under acidic conditions.
SAMPLE HANDLING
& PRESERVATION: Ozone is extremely unstable in aqueous solutions. Test must be performed immediately and the
sample must not be agitated.
INTERFERENCES: Manganese at any level interferes.
