scandium yttrium separation

  • A novel ammonium ionic liquid based extraction …

    Ionic liquid (IL)-based extraction is a promising high-efficiency and environmentally benign separation technology. Imidazolium ILs lose their cations or anions to aqueous phase during extraction, the release lead to water pollution.

  • Separation of scandium, yttrium and lanthanum in high ...

    The separation of scandium, yttrium and lanthanum was performed by high performance centrifugal partition chromatography employing the stationary phase of a heptane solution of CA-12 and the mobile phase of an aqueous chloroacetate buffer. The extractability of CA-12 for Sc, Y and La was different in the mobile phase with different …

  • Lanthanide - Wikipedia

    Etymology. Together with the two elements at the top of group 3, scandium and yttrium, the trivial name "rare earths" is sometimes used to describe all the lanthanides; a definition of rare earths including the group 3, lanthanide, and actinide elements is also occasionally seen, and rarely Sc + Y + lanthanides + thorium.

  • Rare-earth element - Wikipedia

    A rare-earth element (REE) or rare-earth metal (REM), as defined by IUPAC, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium.
