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.
