MSDS (Material Safety Data Sheet)
Test strips and reagent for the detection and semi-quantitative determination of aluminum ions
Aluminum compounds are used as fillers; also as flocculating agents in water works, swimming pools, paper mills, etc. The test, which is largely interference-free, can be directly used to check the integrity and efficiency of filtering systems as part of a general plan of in-process controls.
Wastewater discharged from aluminum smelting and processing plants requires regular monitoring, as aluminum does great harm to fish and other aquatic organisms.
Significant quantities of aluminum may find their way into wine and beer from damaged aluminum casks, etc. The illicit use of alum or other aluminum salts for fining and of preservatives containing aluminum also raises levels of aluminum. As little as 10mg/l aluminum can spoil wine. Concentrations of 10-20mg/l cause beer and wine to become cloudy and give it a characteristic harsh metallic taste.
Aluminum ions are converted by reaction with an alkali into aluminate, which forms a red lake with the ammonium salt of aurintricarboxylic acid. The test is highly sensitive and largely interference-free.
0 - 10 - 25 - 50 - 100 - 250mg/l (ppm) Al3+
The reaction zone is initially deep red. This is due to the reagent used. The final color is only achieved once the reaction has taken place.
Keep reagent 1 (47% potassium hydroxide solution) away from the skin. In the event of contact, rinse well immediately with plenty of water. Seek immediate medical attention if substance enters the eye.
There is no interference at less than:
| 1000mg/l | Br–, BrO3–, Cl–, ClO3–, ClO4–, [Fe(CN)6]3–/4–, IO3–, IO4–, Mo7O246–NO2–, NO3–, SCN–, SeO32–, SO42––, S2O32–, S2O82–, ascorbate, oxalate or tartrate. |
| 500mg/l | CN–, CrO42–, OCN–, S2O42–, VO3–, acetate, citrate, succinate |
| 250mg/l | F–, N3-, S2O52–, WO42– |
| 100mg/l | MnO4-, PO43–, S2–, SO32– |
There is no interference at less than:
| 1000mg/l | Ag+, As3+, Au3+, Ba2+, Bi3+, Ca2+, Cd2+, Ce3+/4+, Co2+, Cr3+, Hg+, Hg2+, Mg2+, Mn2+, NH4+, Pb2+, Rb+, Sb3+, Sn2+, Sr2+, Tl+, Ti4+, Zn2+, Zr4+ |
| 50mg/l | Fe2+/3+ |
| 25mg/l | VO2+ |
| 10mg/l | Cu2+ |
| 2mg/l | Be2+ |
Most of the potential interferences listed above can be avoided by passing the sample solution through an ion exchanger as follows:
Allow 10ml of sample solution to trickle slowly (1 drop per second) through a glass column (diameter 5-10 mm) containing 1 g of Amberlite® IRA400 strong-base anion exchanger. Add 5 drops of reagent 1 to 5ml of the eluate and pass slowly (1 drop per second) through a second column containing 1 g of Amberlite® IR120 strong-acid cation exchanger. Perform the determination, starting at point 3 of the directions.
