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
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, sulfide, thiosulfate,
sulfide and orthophosphate will interfere.
