Chromatographic separation of rare earth elements
Rare-earth elements (REEs) are a group of 17 chemical elements in the periodic table, namely scandium (Sc), Yttrium (Y), and 15 lanthanides. The term “rare earths” name was first used in 1827 by Swedish chemist, Carl Axel Arrhenius, but the elements themselves were not discovered until late 18-1......
