--- Added 3 sets of standard solution preparation (see 4.8, 4.9, 4.10);
--- Revised the method of preparation and preparation of the sample (see Chapter 6, Chapter 6 of the.2009 edition);
--- Modified the amount of potassium carbonate-boric acid mixed flux (see 7.4.1.2, 7.4 of.2009 edition);
--- Modified the preparation of the calibration solution (see 7.4.2, 7.5 of the.2009 edition);
--- Revised the determination and representation of the analysis results (see Chapter 8, Chapter 8 of the.2009 edition);
--- Replace the allowable difference with the reproducibility limit r and the reproducibility limit R of the inter-laboratory precision test data statistics (see Chapter 9,
Chapter 9 of the.2009 edition).

3 Principle
After heating most of the sample with nitric acid, it is filtered, and the filtrate is stored as a main liquid; after the residue is burned, it is melted with potassium carbonate-boric acid mixed flux.
The solution is immersed in hydrochloric acid and hydrochloric acid, and the obtained solution is combined with the main solution to make a constant volume. Introduce the test solution into an inductively coupled plasma atomic emission spectrometer to measure each element
The intensity of the corresponding wavelength is calculated according to the calibration curve regression equation.
4 reagents and materials
In the analysis, unless otherwise stated, only approved high-grade pure reagents and distilled water of Grade II and above in accordance with GB/T 6682 are used.
Or deionized water or water of equivalent purity.
4.1 Vanadium pentoxide, the purity is not less than 99.99%.
4.2 Potassium carbonate-boric acid mixed flux.
The fine anhydrous potassium carbonate and boric acid were mixed at a mass ratio of 1.1 and stored in a desiccator.
