Aluminium
Test kit for performing colorimetric tests
on aluminium ions in surface water and sewage
Method:
Determination with chromazurol S
Measurement range:
0.10–0.50 mg/L Al
Contents of test kit (*refill pack):
sufficient for 50 tests
12 mL Al-2*
28 mL Al-3*
Hazard warning:
This test does not contain any harmful substances which must be spe-
cially labelled as hazardous.
Instructions for use:
also refer to the pictogram on the back of the color chart
1. 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.
2. Add 1 level measuring spoon of Al-1, seal the glass and shake.
3. Add 4 drops of Al-2, seal the glass and mix.
4. Add 10 drops of Al-3, seal the glass and mix
5. Open the glass after 15 min and place it on position B in the com-
parator.
6. Slide the comparator until the colors match in the inspection hole on
top. Check the measurement reading in the recess on the compara-
tor reed. Mid-values can be estimated.
7. After use, rinse out both measuring glasses thoroughly and seal
them.
The method can be applied also for the analysis of sea water after dilu-
tion (1+9).
Disposing of the samples:
The used analysis specimens can be flushed down the drain with tap
water and channelled off to the local sewage treatment works.
Interferences:
The following ions will not interfere:
≤ 1000 mg/L Ca
≤ 50 mg/L SO
≤ 1 mg/L Cu
