3 Principle
The sample is decomposed in a polytetrafluoroethylene crucible with hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid, and the sample solution is atomized in a nitric acid medium.
Introduced by the carrier gas into the argon plasma torch flame, the atoms of the element to be tested are excited to emit a characteristic spectrum, and within a certain range, the elements to be tested in the test solution
The concentration is proportional to the intensity of the characteristic line, and the concentration of the element to be tested in the test solution is calculated by measuring the signal intensity of the characteristic line.
4 reagents and materials
Caution - Hydrofluoric acid, perchloric acid, nitric acid are toxic and corrosive. Wear anti-corrosion gloves during operation to prevent contact with skin.
4.1 Argon [φ(Ar) ≥ 99.996%].
4.2 Water, in line with GB/T 6682, Class III and above water.
4.3 Hydrochloric acid, ρ=1.19g/mL, analytically pure.
4.4 Nitric acid, ρ = 1.42 g/mL, analytically pure.
4.5 Hydrofluoric acid, ρ = 1.15 g/mL, analytically pure.
4.6 Perchloric acid, ρ=1.67g/mL, analytically pure.
4.7 Iron oxide, analytically pure.
4.8 Lead standard stock solution (1000μg/mL)
Weigh 1.0000 g of metal lead (purity >99.9%), add 20 mL of water and 20 mL of nitric acid (see 4.4), and dissolve by heating. After cooling, will
Transfer the solution to a 1000 mL volumetric flask, dilute to the mark with water, and mix. 1 mL of this solution contained 1000 μg of lead.
