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 iron content. Water softening
resins are effective 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: 0.00–10.00 ppm
METHOD: Ferric iron is reduced to ferrous iron and subsequently forms
a colored complex with 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.
The pH 2-3 will prevent depositation of iron on the
container walls. Samples should be analyzed as soon as
possible.
