Scope

This standard specifies the method for determining the total amount of ionic rare earth elements in ionic rare earth raw ores.
This standard is applicable to the determination of the total amount of ionic rare earth elements in ionic rare earth raw ores, and it includes three methods: Method 1, inductively coupled plasma mass spectrometry; Method 2, inductively coupled plasma atomic emission spectrometry; and Method 3, EDTA titration. The determination range of Method 1 is 0.010% to 0.50%; the determination range of Method 2 is 0.020% to 0.50%; and the determination range of Method 3 is 0.020% to 0.50%. Among them, Method 3 is not suitable for determining the samples with iron content greater than 10% after leaching or copper content greater than 5%.
