Rapid, high-purity, lanthanide separations using HPLC

Purification of a 166mHo solution by successive high-performance liquid chromatography and gravitational chromatography for half-life determination

“…High-performance liquid chromatography (HPLC) based on different separation modes, is a highly efficient and selective technique for their separation [8][9][10][11][12][13]. Gravitational column chromatography loaded with extractant resin is also utilized to perform lanthanide separation [14][15][16].…”

Radiochemical studies relevant to cyclotron production of the therapeutic radionuclide 167Tm

“…In recent years separation of thulium and erbium were reported with resin containing 1-hexyl-4-ethyloctyl isopropylphosphonic acid (HEOPPA) by Wang et al [16], α-hydroxyisobutyric acid (α-HIB) by Schwantes et al [17], a mixture of acidic phosphorus based reagents by Xianglan et al [18] and ion imprinted polymer particles via solid phase extraction by Kala et al [19].…”

Design and synthesis of chelating diamide sorbents for the separation of lanthanides

“…Due to the very similar chemical properties of lanthanides (generally trivalent cations with similar in ionic radii [3,13,14]), separating the lanthanides from one another can be quite difficult [14][15][16]. Many efforts have been made in an attempt to achieve these lanthanide separations.…”
