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. Table 1 Determination range of elements Element measurement range/(mg/kg) Element measurement range/(mg/kg) Calcium 1~200 Nickel 0.5~100 Chromium 1~100 lead 1~100 Copper 1~100 Silicon 1~200 Iron 1~100 Titanium 0.5~100 镧0.5~100 Vanadium 0.5~100 Magnesium 1~100 钇1~100 Manganese 0.5~100 zinc 1~100 Sodium 1~200 Zirconium 0.5~200

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. ......
