Test 0-98 NANOCOLOR Aluminum 07 Test Tube
Method:
Photometric determination with eriochrome cyanine R
Contents of reagent set:
19 test tubes Aluminum 07 with NANOFIX
1 test tube with 11 mL Aluminum 07 R2
1 test tube with 11 mL Aluminum 07 R3
1 test tube with 11 mL Aluminum 07 R4
1 test tube with blank value ”NULL”
Hazard warning:
This test does not contain any harmful substances which must be specially
labelled as hazardous.
Preliminary tests:
If the order of magnitude of the concentration in a sample is not known, a
preliminary test with QUANTOFIX® Aluminum (5–500 mg/L Al3+, REF 913 07)
rapidly gives this information. From the order of magnitude the required
dilution can be calculated and prepared directly.
Interferences:
Fluoride interferes.
Turbid samples are to be filtered (membrane filter 0.45 μm, REF 916 50). The
total Aluminum can be determined with NANOCOLOR® NanOx Metal (REF 918 978) and
microwave decompo-sition.
The following ions will not interfere:
≤ 100 mg/L SiO2
≤ 10 mg/L Cu2+, Fe2/3+, Mn2+, Ni2+, Zn2+
≤ 5 mg/L Cr2+, Cd2+
≤ 1 mg/L Co2+
The method can be applied also for the analysis of sea water.
Procedure:
Requisite accessories: piston pipette with tips
Open test tube, add
500 μL (= 0.5 mL) R2,
500 μL (= 0.5 mL) R3 and
4.0 mL sample solution (the pH value of the sample must be between pH 3 and
6), close and mix.
Open test tube again, add
500 μL (= 0.5 mL) R4, close and mix.
Clean outside of test tube and measure after 5 min.
Adjust photometer to zero by using blank value “NULL”.
Measurement:
For NANOCOLOR® photometers and PF-12 see manual, test 0-98.
Measurement when samples are colored or turbid:
For all NANOCOLOR® photometers see manual, use key for correction value.
Photometers of other manufacturers:
For other photometers check whether measurement of round glass tubes is
possible. Verify factor for each type of instrument by measuring standard
solutions. The factor depends strongly on the wavelength.
