Determination of arsenic, cadmium, copper, nickel,
lead, zinc in lead ore for import and export -
Inductively couple plasma atomic emission
spectrometric method
1 Scope
This standard specifies the method for the determination of arsenic, cadmium,
copper, nickel, lead, zinc in lead ores for import and export by inductively
coupled plasma atomic emission spectrometry.
This standard applies to the determination of arsenic, cadmium, copper, nickel,
lead, zinc content in lead ores for import and export. The measurement range
of each element is as shown in Table 1.
Table 1 -- Measurement range of each element
2 Normative references
The following documents are essential to the application of this document. For
the dated documents, only the versions with the dates indicated are applicable
to this document; for the undated documents, only the latest version (including
all the amendments) are applicable to this standard.

Mass
fraction, %
3 Method summary
The sample was dissolved by acid dissolution method. The element emission
intensity was measured by plasma emission spectrometer.
4 Reagent
Unless otherwise specified, the reagents used are all analytical reagents and
above; the water is grade-2 water that meets the requirements of GB/T 6682.
4.1 Hydrochloric acid (ρ = 1.19 g/mL).
4.2 Nitric acid (ρ = 1.42 g/mL).
4.3 Nitric acid (1 + 9).
4.4 Lead standard stock solution. Accurately weigh 8.00 g of lead nitrate; use
400 mL of nitric acid (4.3) to dissolve it; transfer it into a 1000 mL volumetric
flask; dilute to the mark; 1 mL of this solution contains 5 mg of lead.
4.6 Mixed standard solution. Pipette each element standard stock solution (4.5)
into a 100 mL volumetric flask; use nitric acid (4.3) to dilute it to the mark; mix
well. The amount of each tested element in 1 mL of this solution is as shown in
Appendix A.
5 Instrument
5.1 Inductively coupled plasma atomic emission spectrometer.
6 Specimen
The specimen is passed through a 149 μm screen and dried in an oven at 60 °C
for 4 hours; then placed in a desiccator to cool to room temperature to prepare
for use.
7 Analytical procedures
7.1 Pre-treatment of samples
Weigh about 0.2 g of sample, accurate to 0.0001 g. Place it in a 250 mL beaker.
Use a small amount of water to wet it. Add 10 mL of hydrochloric acid (4.1).
Leave it at room temperature for about 30 min.
7.2 Determination
7.2.1 The analytical line is as shown in Table 2.
7.2.3 Introduce the sample solution to be tested into the plasma in turn, to
respectively measure the spectral intensity at the analytical line of each tested
element.
8 Calculation of analytical results
Calculate the mass fraction of the measured element according to formula (1);
the value is expressed in %.
9 Precision
8 laboratories conduct method precision tests on 7 levels of samples and
perform statistics in accordance with GB/T 6379.2.The results are as shown in
Table 3.
