1 Scope
This standard specifies platinum (Pt), ruthenium (Ru), iridium (Ir), palladium (Pd), gold (Au), silver (Ag), copper (Cu), iron (Fe), nickel (Ni) in tantalum powder. ),
A method for measuring the amounts of aluminum (Al), lead (Pb), manganese (Mn), magnesium (Mg), tin (Sn), zinc (Zn), and silicon (Si).
This standard applies to the determination of platinum, antimony, bismuth, palladium, gold, silver, copper, iron, nickel, aluminum, lead, manganese, magnesium, tin, zinc and silicon in bismuth powder. Element measurement
The range is shown in Table 1.
Table 1 Measurement range
Element determination range /%
Mg, Al, Mn, Ni, Cu, Zn, Ru, Ag, Pd, Sn, Ir, Pt, Au, Pb 0.00005~0.050
Fe 0.00010~0.050
Si 0.0005~0.050
2 Principle of the method
The sample was dissolved with hydrochloric acid-hydrogen peroxide, iron was used as the internal standard, and silicon was used as the internal standard. The co-location was determined in the collision/reaction mode.
The signal intensity (cps) of the prime; palladium, silver, lanthanum, aluminum, copper, nickel, magnesium, manganese, zinc with 钇 as the internal standard, tin with indium as the internal standard, bismuth, platinum, gold, lead and
Internal standard, the cps value of its isotope is determined in normal working mode.
3 reagents
3.1 Potassium hydroxide.
3.2 Potassium chlorate.
3.3 Nitric acid (ρ=1.42g/mL), MOS grade.
3.4 Hydrochloric acid (ρ=1.19g/mL), MOS grade.
3.5 Hydrogen peroxide (volume fraction 30%).
3.6 Mixed acid. Three units of hydrochloric acid (3.4) are mixed with one unit volume of nitric acid (3.3).
3.7 Silver standard storage solution. Weigh 0.1000g of metallic silver (mass fraction ≥99.99%) and place it in a 100mL Teflon beaker.
Add 2mL of nitric acid (3.3), dissolve at low temperature and dissolve completely, transfer to a 100mL volumetric flask, add 10mL of nitric acid (3.3), dilute with water to
Scale. Mix well. 1 mL of this solution contained 1.0 mg of silver.
3.8 Palladium standard storage solution. Weigh 0.1000g of metal palladium (mass fraction ≥99.99%) and place it in a 100mL Teflon beaker.
Add 4mL mixed acid (3.6), dissolve completely at low temperature, transfer to a 100mL volumetric flask, add 10mL hydrochloric acid (3.4), dilute with water
To the scale. Mix well. 1 mL of this solution contained 1.0 mg of palladium.
3.9 Platinum standard storage solution. Weigh 0.1000g of metal platinum (mass fraction ≥99.99%) and place it in a 100mL Teflon beaker.
