Iron Test Kit

ISTR3834NR2

07/02

PRINTED

ITALY

Generally, ground and surface water contains no more than

1 mg/L (ppm) iron; but due to mining and industrial

drainage, higher levels of iron have been observed. Iron in

water appears to be more of a nuisance than a hazard.

The presence of iron can stain laundry and give water a

bittersweet taste.

The Hanna Test Kit determines the iron concentration in

water by conversion of the ferrous (Fe

) state. The test is

fast, easy and safe. The color cube makes it simple to obtain

the iron level in water.

SIGNIFICANCE AND USE

CHEMICAL REACTION

Iron can exist as ferrous (Fe

) or ferric (Fe

) ions. The

Hanna Test Kit determines total iron levels in water via a

colorimetric method. First all ferric ions are reduced by

sodium sulfite to ferrous ions. Phenanthroline complexes with

ferrous ion to form an orange colored solution. The color

intensity of the solution determines the iron concentration.

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT

• Remove the cap from the plastic vessel. Rinse the plastic

vessel with water sample, fill it to 10 mL mark.

• Add 1 packet of reagent HI 3834-0.

• Replace the cap and mix solution until solids dissolve.

• Remove the cap and transfer the solution into the color

comparator cube. Let set for 4 minutes.

• Determine which color matches the solution in the cube

and record the result as mg/L (ppm) iron.
