1 Scope
This standard specifies the determination of trace metals in high purity alumina powder by inductively coupled plasma optical emission spectroscopy (ICP-OES).
The method of content.
This standard applies to high purity alumina powder (the mass fraction of alumina content ranges from 99.9% to 99.995%) in calcium, chromium,
Determination of trace metal elements such as copper, iron, strontium, magnesium, manganese, sodium, nickel, lead, silicon, titanium, vanadium, niobium, zinc and zirconium. See the measurement range of each element
Table 1.

2 Normative references
The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article.
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
Preparation of standard solution for GB/T 602 chemical reagent impurity determination

3 Principle
After the sample is heated and pressurized by sulfuric acid to form a solution, it is excited in the plasma torch flame to emit a characteristic analysis line of the contained element.
The content of the corresponding element is determined according to the intensity of the line of the element to be tested.
