*WARNING:

 Reagents marked with an * are considered to be potential health hazards. To 

view or print a Safety Data Sheet (SDS) for these reagents go to www.lamotte.com. 
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, 
contact LaMotte by email, phone or fax.

Emergency information for all LaMotte reagents is available from Chem-Tel: 
(US, 1-800-255-3924) (International, call collect, 813-248-0585).

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.
