Principle 3
The samples were crushed using nitric acid digestion, the resulting solution was diluted with water directly after inductively coupled plasma mass spectrometry (ICP-
MS) method for the determination, to which the mass to charge lead, arsenic, chromium, cadmium determination of element concentrations than the strength of its quantitative relationship.
4 Reagents and materials
This standard reagents and water in the absence of other specified requirements, refer to pure class distinctions or through sub-boiling distilled chemicals and
GB/T 6682 specified in a water. Minor amounts of other reagents (amount not to exceed 1mL) can be used analytically pure.
4.1 concentrated nitric acid. ρ = 1.42g/mL, 65% (mass fraction).
4.2 nitric acid solution (298).
4.3 Standard solution. lead, cadmium, chromium, arsenic standard solution prepared according to GB/T 602 method, or direct use of the elements of a standard certificate
Solution. Lead, cadmium, chromium concentration of arsenic standard solution are 1.000g/L.
