GB/T 18115.2-2020 Chemical analysis methods of rare earth impurities in rare earth metals and their oxides—Part 2:Determination of lanthanum,praseodymium,neodymium,samarium,europium,gadolinium,terbium,dysprosium,holmium,erbium,thulium,ytterbium,lutetium and yttrium content in cerium metal and oxide

Scope

This part of GB/T 18115 specifies the determination methods for the contents of lanthanum oxide, praseodymium oxide, neodymium oxide, samarium oxide, europium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, erbium oxide, thulium oxide, yttrium oxide in cerium oxide.
This part is applicable to the determination of the contents of lanthanum oxide, praseodymium oxide, neodymium oxide, samarium oxide, europium oxide, gadolinium oxide, terbium oxide, dysprosium oxide, holmium oxide, erbium oxide, thulium oxide, yttrium oxide in cerium oxide.
This part is also applicable to the determination of the contents of lanthanum, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, yttrium in metallic cerium.
This part includes three methods: Method 1 inductively coupled plasma emission spectrometry, Method 2 inductively coupled plasma mass spectrometry, and Method 3 inductively coupled plasma tandem mass spectrometry. The determination range of Method 1 is shown in Table 1, the determination range of Method 2 is shown in Table 2, and the determination range of Method 3 is shown in Table 3.
