Most natural waters contain some iron. Its presence may vary from small traces<br />
to very large amounts in water which is contaminated by acid mine wastes. For<br />
domestic use, the concentration should not exceed 0.2 ppm and for some<br />
industrial applications not even a trace of iron can be tolerated. There are<br />
many means available for removing or reducing iron content. Water softening<br />
resins are effective for removing small amounts of iron and special ion<br />
exchange materials are selective for iron removal. High concentrations of iron<br />
can be removed by such chemical processes as oxidation and lime or lime-soda<br />
softening. Because of the many means of removing or reducing the amount of<br />
iron in water, the particular method employed will depend largely on the form<br />
of iron which is present and the end use of the treated water.<br />
APPLICATION: Drinking, surface, and saline waters; domestic and industrial<br />
wastes.<br />
RANGE: 0.00–10.00 ppm<br />
METHOD: Ferric iron is reduced to ferrous iron and subsequently forms<br />
a colored complex with bipyridyl for a quantitative measure<br />
of total iron.<br />
