Alkalinity is a measure of the acid-neutralizing capacity of water that enables it
to resist abrupt changes in pH. It is the sum of all titratable bases. Alkalinity is
significant in maintaining proper pH levels in natural water; water used for
irrigation, swimming pools, industrial processes and wastewater treatment
processes.
The presence of buffering materials in natural waters helps to neutralize acids
as they are added to, or created in, the water ecosystem. A Total Alkalinity of
100 to 200 ppm will stabilize the pH level in a stream. In swimming pools, total
alkalinity is commonly known as a pH stabilizer because, when the alkalinity is
at a proper level, a consistent pH level can be maintained while treatment
chemicals or fresh make-up water is added. In industrial situations, alkalinity is
an important factor in preventing fluctuating pH levels that can damage
equipment and corrode pipes.
APPLICATION:
Drinking and surface water and swimming pool water
RANGE:
0–200 ppm as CaCO

SMART Spectro
METHOD:
The sample is added to a buffered indicator reagent. The
color that develops, ranging from yellow to blue, will
indicate the amount of alkalinity in the sample.
SAMPLE
HANDLING &
PRESERVATION:
Samples should be analyzed as soon as possible after
collection. Sample may be refrigerated for 24 hours.
INTERFERENCES:
Quats and poly quats at high concentrations will interfere.
