3 Method summary
After the sample digestion, measured spectral intensity in the corresponding element ICP-OES wavelength, using the standard curve internal standard.
4 Reagents and materials
Unless otherwise specified, all reagents superior grade pure water was used a water line with GB/T 6682 stipulated.
Nitrate 4.1 (MOS level, 65%).
4.2 Hydrogen peroxide (30% aqueous solution).
4.3 nitric acid solution (595). Measure 50mL of nitric acid (4.1) slowly added to 950mL of water.
4.4 boron standard stock solution (1000μg/mL). direct use element standard solution standard material certificates are valid within the standard concentration
Of 1000μg/mL.
4.5 yttrium standard stock solution (100μg/mL). As ICP-OES detection of an internal standard, the direct use of reference material certificates valid
