2 method summary

The samples were dissolved in hydrochloric acid and nitric acid, and the contents of magnesium, aluminum, silicon, chromium, manganese, iron, nickel, copper were measured by inductively coupled plasma mass spectrometry. Zinc, ruthenium, rhodium, silver, tin, iridium, platinum, gold, lead and bismuth.

3 Reagents and Materials

Unless otherwise stated, only primary water identified as excellent grade pure reagent and having a resistivity of not more than 18.2 MΩ · cm-1 was used in the analysis. 3.1 hydrochloric acid (ρ1.19g/mL), MOS grade. 3.2 nitric acid (ρ1.42g/mL), the MOS level. 3.3 Hydrogen peroxide (ρ1.44g/mL), MOS grade. 3.4 hydrochloric acid (1 1), with the current distribution. 3.5 nitric acid (1 1), with the current distribution. 3.6 hydrochloric acid (1 4), with the current distribution. 3.7 mixed acid. 3 volumes of hydrochloric acid (3.1) and 1 volume nitric acid (3.2) mix, with the current distribution. 3.8 magnesium standard storage solution. magnesium oxide (wMgO ≥ 99.99%) in the first 600 ℃ for 1h, placed in a dryer to cool to room temperature. Said Take 0.1658g magnesia in a.200mL beaker, add a small amount of water wetting, add 5mL hydrochloric acid (3.4), cover the surface dish, dissolve completely, Into the 100mL volumetric flask, diluted with water to the mark, mix. 1 mL of this solution contains 1000 g of magnesium. ...
