Method for analysis of copper cathode —The optical emission spectrometry
1 Scope
This standard specifies the determination method of arsenic, antimony, bismuth, sulfur, selenium, tellurium, iron, silver, tin, nickel, lead, zinc, chromium, cadmium, cobalt, silicon, phosphorus and manganese in copper cathode.
This standard is applicable to the determination of arsenic, antimony, bismuth, sulfur, selenium, tellurium, iron, silver, tin, nickel, lead, zinc, chromium, cadmium, cobalt, silicon, phosphorus and manganese in copper cathode. The determination range is
2 Normative reference
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB/T 467-2010 Copper cathode
3 Summary of method
The power supply excites periodically between the electrode and the surface of the sample, and the sample atoms are excited to emit characteristic spectrum. The YS/T464-20XX
spectral intensity is a function of element concentration. The computer automatically collects the excitation intensity value and calculates the element content.
4 Materials
4.1 High purity graphite crucible with cover. Reference size and specifications are shown in Figure 1 (unit: mm).
4.2 Curve shall be calibrated with high and low standard samples.
4.3 Standard sample: Certified copper cathode spectral standard sample, whose impurity elements content range covers or partially covers the determination range of this method.
4.4 Argon: Ar > 99.998%, O2 < 0.000 2%,

5 Apparatus
5.1 Lathe/milling machine and cutter.
5.2 High temperature box resistance furnace.
5.3 Optical emission spectrometer (See Annexes A for the working conditions of the instrument).
