2 method summary
Samples hydrochloric acid, nitric acid, hydrofluoric acid and perchloric acid decomposition. Nitric acid dissolved salts, in dilute nitric acid medium, in the inductively coupled plasma
At the wavelength of each element selected by the emission spectrometer, the emission intensity was measured, and the mass fraction of each element was calculated by the working curve method.
3 reagent
Unless otherwise noted, only reagents identified as superior grade pure are used in the analysis, all water used is distilled or deionized water or equivalent
Water.
3.1 Hydrochloric acid (p = 1.19 g/mL).
3.2 Nitric acid (p = 1.42 g/mL).
Hydrofluoric acid (ρ = 1.15 g/mL).
3.4 Perchloric acid (ρ = 1.67g/mL).
3.5 Hydrochloric acid (1 1).
Nitric acid (1 1).
3.7 Standard storage solution of copper Weigh 1.0000g of metallic copper (wCu ≥ 99.99%), placed in 300mL beaker, cover the table, add slowly
Into 50mL nitric acid (3.6), dissolved at low temperature, get rid of nitrogen oxides, removed and cooled to room temperature, washed with water and table glass table wall, into
1000mL volumetric flask, add 50mL of nitric acid (3.6), diluted with water to the mark, mix well. 1 mL of this solution contains 1 mg of copper.
3.8 Lead standard stock solution Weigh 1.0000g metallic lead (wPb ≥ 99.99%), placed in 300mL beaker, cover the table, slowly add
