Dear Customer,
Thank you for choosing a Hanna Product.
Please read the instructions carefully before using the
chemical test kit. It will provide you with the necessary
information for a correct use of the kit.
Remove the chemical test kit from the packing material and
examine it carefully to make sure that no damage has
occurred during shipping. If there is any noticeable damage, notify your Dealer or the nearest Hanna office
immediately.
Each kit is supplied with:
HI 3834-0 Reagent, packets (100 pcs);
•
1 color comparator cube;
•
1 plastic vessel (20 mL).
•
Range 0 to 5 mg/L (ppm) Iron
Smallest Increment 1 mg/L (ppm) Iron
Analysis Method Colorimetric
Sample Size 10 mL
Number of Tests 100 (average)
SIGNIFICANCE AND USE
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 (Fe2+) state. The test is
fast, easy and safe. The color cube makes it simple to
obtain the iron level in water.
CHEMICAL REACTION
Iron can exist as ferrous (Fe2+) or ferric (Fe3+) 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.
