3 method summary
The sample was decomposed with hydrobromic acid, hydrogen peroxide and hydrochloric acid in a dilute hydrochloric acid medium at 309.3 nm of the electrothermal atomic absorption spectrometer with a plug
Man (or deuterium lamp) subtracts the background absorbance and measures the absorbance of aluminum.
4 reagent
Unless otherwise stated, the analytical waters are all Grade 1 waters. After all the vessels used in the experiment were thoroughly soaked in hydrochloric acid (1.19), they were washed with water.
4.1 Hydrochloric acid (mos grade).
4.2 Nitric acid (mos level).
4.3 hydrobromic acid Purified by sub-boiling distillation with analytical hydrobromic acid (≥40.0%).
Hydrogen peroxide (BV Ⅲ level).
4.5 Hydrochloric acid (1 4).
4.6 aluminum standard stock solution Weigh 1.0000g aluminum metal (wAl ≥ 99.99%), placed in 250mL high-type beaker, add 10mL salt
Acid (4.1) and 3mL of nitric acid (4.2), cover the watch glass, low temperature heating on a hot plate to completely dissolve, remove, cool, wash the watch glass with water
And cup wall, remove the watch glass, move into 1000mL volumetric flask, add 25mL hydrochloric acid (4.1), diluted with water to the mark, and mix. This solution
1 mL contains 1 mg aluminum.
4.7 Aluminum standard solution A. Pipette 10.00mL aluminum standard stock solution (4.6) in.200mL volumetric flask, add 10mL hydrochloric acid (4.1),
Dilute to the mark with water and mix well. 1 mL of this solution contained 50 μg of aluminum.
4.8 aluminum standard solution B. Pipette 5.00mL aluminum standard solution (4.7) in 100mL volumetric flask, add 5mL hydrochloric acid (4.1), diluted with water
Release to the mark, mix well. This solution 1 mL contains 2.5 μg of aluminum.
4.9 Cotton wool - pulp, treated with hydrochloric acid (4.5) 4 times.
