TEST METHODS SPECIFICATIONS
INTRODUCTION
Most natural waters contain some iron. The concentration 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 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 to 5.00 ppm Iron
METHOD
Ferric iron is reduced to ferrous iron and subsequently forms a colored
complex with phenanthroline for a quantitative measure of total iron.
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 after collection since ferrous iron undergoes oxidation to ferric iron.
INTERFERENCES
Strong oxidizing agents, cyanide, nitrite, phosphates, chromium, and zinc in
concentrations exceeding 10 times that of iron; cobalt and copper in excess
of 5 mg/L, and nickel in excess of 2 mg/L. Bismuth, cadmium, mercury,
molybdate, and silver precipitate phenanthroline.

NOTE: The meter will remember the last scanned blank reading. It is not
necessary to scan a blank each time the test is performed. To use the
previous blank reading, instead of scanning a new one, scroll to Scan Sample
and proceed. For the most accurate results, the meter should be blanked
before each test and the same tube should be used for the blank and the
reacted sample.
NOTE: For the best possible results, carry a reagent blank through the
procedure.
After scanning the blank, perform the test procedure on clear,
colorless,
distilled or deioized water. Subtract results of regent blank from all
subsequent test results.

CALIBRATION
STANDARDS
The meter should be calibrated with iron standards. The calibration should be
done with a distilled or deionized water blank and one iron standard of known
concentration. The concentration of the calibration standard should be similar
to the expected concentration of the sample that will be tested.
CALIBRATION PROCEDURE
1. Press and briefly hold to
turn the meter on. The LaMotte
logo screen will appear for about
3 seconds and the Main Menu
will appear.
