Like chlorine, bromine is an effective germicidal agent employed in drinking
water treatment, pool and spa water sanitization, food service sanitation, and
other public health applications.
APPLICATION: Drinking, surface, and saline waters; swimming pool water;
domestic and industrial waters and wastes.
RANGE: 0.0–22.0 ppm Bromine
METHOD: In buffered sample bromine reacts with diethyl-p-phenylene
diamine (DPD) to produce a pink-red color in proportion to
the concentration of bromine present.
SAMPLE
HANDLING &
PRESERVATION: Bromine in aqueous solutions is not stable, and the bromine
content of samples or solutions, particularly weak solutions,
will rapidly decrease. Exposure to sunlight or agitation will
accelerate the reduction of bromine present in such
solutions. For best results start analysis immediately after
sampling. Samples to be analyzed for bromine cannot be
preserved or stored.
