Test Procedures
APPLICATION:
Drinking, surface, and saline waters; domestic and industrial
wastes.
RANGE:
0.00–10.00 ppm Iron
MDL:
0.07 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.
INTERFERENCES:
