2 principle of the method
The contents of rhodium, silver, copper, nickel, lead and tin were determined by using cesium as internal standard, palladium, iridium and gold.
The ruthenium was used as an internal standard to determine the signal intensity of its isotope in normal operating mode.
3 reagent
Unless otherwise specified, only the primary reagent identified as the analytical reagent and the resistivity of not more than 18.2 MΩ · cm-1 is used in the analysis.
3.1 nitric acid (ρ1.42g/mL), MOS grade.
3.2 hydrochloric acid (ρ1.19g/mL), MOS grade.
3.3 Hydrochloric acid (1 1).
3.4 Hydrogen peroxide (ρ1.44g/mL), MOS grade.
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 (3.2) and 1 volume of nitric acid (3.1) mix, with the current distribution.
3.8 silver standard storage solution. Weigh 0.5000g metal silver (wAg ≥ 99.99%), placed in.200mL beaker, add 30mL nitric acid
(3.1), cover the surface dish, heat dissolved, cooled, into the 500mL volumetric flask, diluted with water to the mark, mix. This solution 1mL
