TEST METHODS SPECIFICATIONS

„ APPLICATION

Drinking water supplies and distribution systems, swimming pool and spas, sewage and
chlorinated waste waters, process waters and sanitizing solutions.

„ RANGE

0 to 4.0 ppm Chlorine (may be extended by dilution)
0 to 7.0 ppm Bromine (may be extended by dilution)

„ METHOD

In the absence of Iodide, Free Available Chlorine reacts instantly with the buffered diethyl-p-
phenylenediamine indicator (DPD) to produce a pink-red color in proportion to the amount of
chlorine present. Subsequent addition of potassium iodide produces a rapid color response from
the combined forms of chlorine (chloramines). In buffered samples, bromine reacts with disthyl-
p-phenylene diamine (DPD) to produce a pink-red color in proportion to the concentration of
bromine present.
„ HANDLING & PRESERVATION
Chlorine and bromine in aqueous solutions, particularly weak solutions, are not stable. Exposure
to sunlight or agitation will accelerate the reduction of chlorine and bromine. For chlorine
samples, fill sample containers to the top and cap tightly. Analyze samples as soon as possible
after collection. Samples to be analyzed for bromine cannot be preserved or stored.

„ INTERFERENCES

The only interfering substance likely to be encountered is oxidized manganese. The extent of this
interference can be determined by treating a sample with sodium arsenite to destroy the chlorine
or bromine present, so that the amount of interference can be estimated. Chlorine, bromine, and
iodine will give a positive result and should be considered an interference unless the test is being
performed specifically for that parameter.
