MACHEREY-NAGEL Iron 1 Performing Colorimetric Tests Kit
Test kit for performing colorimetric tests on iron ions in surface water and sewage
Method
Colorimetric determination of Fe(II) and Fe(III) ions with a triazine derivate
Measurement range
0.04–1.0 mg/L Fe
Contents of test kit (refill pack)
sufficient for 200 tests
- 30 mL Fe-1*
- 2 screw-plug measuring glasses
- 1 slide comparator
- 1 color chart
- 1 plastic syringe 5 mL
- 1 instruction for use
Hazard warning:
Information regarding safety can be found on the box label and in the safety
data sheet. You can download the SDS from www.mn-net.com/SDS.
Instructions for use
Also, refer to the pictogram on the back of the color chart
-
Pour a 5 mL water sample into each of the measuring glasses using the plastic syringe. Place a measuring glass on position A in the comparator.
Only add the reagent to measuring glass B. -
Add 5 drops of Fe-1, seal the glass, and mix.
-
Open the glass after 3 min and place it on position B in the comparator.
-
Slide the comparator until the colors match in the inspection hole on top. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
-
After use, rinse out both measuring glasses thoroughly and seal them.
The reagents can also be used for the photometric evaluation with photometers PF-12 and PF-12Plus.
This technique can be used also for analyzing seawater.
Disposing of the samples:
Information regarding disposal can be found in the safety data sheet. You can
download the SDS from www.mn-net.com/SDS.
Interferences
The following quantities of ions will not interfere: ≤ 5 mg/L Co2+, Ni2+, MoO42–; ≤ 3 mg/L Cu2+.
