Abstract
Rare-earth ores (monazite, ion-adsorption type and xenotime) were analyzed using a coupled analytical method, isotachophoresis-particle induced X-ray emission (ITP-PIXE). The detection limit for each minor rare-earth element in the ores was ca. 0.01 mass% of the total rare-earth elements (TREE), when 200μg of monazite was analyzed. Since yttrium was the major component in ion-adsorption type and xenotime ores, the use of a leading electrolyte containing α-hydroxyisobutyric acid and tartaric acid as complexing agents was effective for the separation of yttrium ion from lanthanide ions.Keywords
