2 Method summary
The sample is digested with hydrochloric acid-potassium chlorate at high temperature and high pressure, and is connected to each element to be tested by inductively coupled plasma atomic emission spectrometry.
The mass fraction of the impurity element is measured and calculated at the wavelength of the wavelength.
3 reagents and materials
3.1 Potassium chlorate.
3.2 Nitric acid (ρ = 1.42 g/mL).
3.3 Hydrochloric acid (ρ = 1.19 g/mL).
3.4 Hydrogen peroxide (30%, volume fraction).
3.5 Mixed acid. Three units of hydrochloric acid (3.3) are mixed with one unit volume of nitric acid (3.2).
3.6 Hydrochloric acid (1 4).
