3.1 Principle
After ashing the coal sample, it is decomposed by nitric acid, perchloric acid and hydrofluoric acid, and kept in a nitric acid medium. After constant volume, the inductively coupled plasma atom is used.
Emission spectrometer measurement.
3.2 Reagents and materials
The reagents used were of excellent grade unless otherwise stated. The water is deionized water or water of comparable purity.
3.2.1 Nitric acid (ρ = 1.42 g/mL).
3.2.2 Perchloric acid (ρ = 1.67 g/mL).
3.2.3 Hydrofluoric acid (ρ=1.16g/mL).
3.2.4 Argon. High purity (99.99%).
3.2.5 Standard stock solution. 15 kinds of single element standard solution can be prepared according to GB/T 602 method, or directly use certified standard solution, its quality
The concentration was 1000 μg/mL.
3.2.6 Mixed standard solution. Take the standard stock solution (3.2.5) of each element in the 100mL volumetric flask according to Table 2, add 5mL nitric acid
