Chloride is one of the major anions found in water and sewage. The presence of
chlorides in large amounts may be due to the natural process of water passing
through salt formations in the earth, or it may be evidence of the intrusion of
seawater or pollution from industrial processes or domestic wastes. The salt
content of water affects the distribution of plant and animal life in an aquatic
system, based on the amount of salt they can tolerate.
APPLICATION: Drinking, surface, and saline waters; domestic and
industrial wastewaters.
RANGE: 0.0–30.0 ppm Chloride
MDL: 0.4 ppm
METHOD: Silver nitrate reacts with chloride to form turbid silver
chloride in proportion to the amount of chloride in the
sample.
SAMPLE
HANDLING &
PRESERVATION:
Collect samples in clean, chemically resistant glass or
plastic containers. No preservative is needed if sample is to
be stored.
INTERFERENCES: Substances in amounts normally found in drinking water
will not interfere. Bromide, iodide, cyanide, sulfi de,
thiosulfate, sulfi de and orthophosphate will interfere.
