3 method summary

The sample is melted with sodium peroxide and sodium hydroxide mixed flux, and leached by a sulfuric acid-hydrochloric acid mixed solution, and the inductively coupled plasma is used after constant volume. The atomic emission spectrometer measures the response intensity of the element to be tested, and determines the content of the element to be tested according to the calibration curve.

4 reagents

Unless otherwise stated, the reagents used were of analytical grade and the water was secondary water as specified in GB/T 6682. 4.1 Hydrochloric acid (ρ = 1.19 g/mL). 4.2 Sulfuric acid (ρ=1.84g/mL). 4.3 sodium peroxide.
