Search for the four digit reagent code number listed on the reagent label, in the contents
list or in the test procedures. Omit any letter that follows or precedes the four digit code
number. For example, if the code is 4450WT-H, search 4450. To obtain a printed copy,

Most natural waters contain some iron. Its presence may vary from small traces to very
large amounts in water which is contaminated by acid mine wastes. For domestic use, the
concentration should not exceed 0.2 ppm and for some industrial applications not even
a trace of iron can be tolerated. There are many means available for removing or reducing
the iron content. Water softening resins are eff ective for removing small amounts of iron
and special ion exchange materials are selective for iron removal. High concentrations
of iron can be removed by such chemical processes as oxidation and lime or lime-soda
softening. Because of the many means of removing or reducing the amount of iron in
water, the particular method employed will depend largely on the form of iron which is
present and the end use of the treated water.
APPLICATION:
Drinking, surface, and saline waters; domestic and industrial
wastes.
RANGE:
0.00–6.00 Iron
MDL:
0.06 ppm
METHOD:
Ferric iron is reduced to ferrous iron and subsequently forms
a colored complex with bipyridyl for a quantitative measure of
total iron.
SAMPLE HANDLING &
PRESERVATION:
The sample container should be cleaned with acid and rinsed
with deionized water. Addition of acid to adjust the sample to
pH 2–3 will prevent deposition of iron on the container walls.
Samples should be analyzed as soon as possible.
INTERFERENCES:
Strong oxidizing agents interfere, as well as copper and cobalt
in excess of 5.0 mg/L.
