Sequential Separation of U, Th, Pb, and Lanthanides with a Single Anion-Exchange Column

Uranium (U), thorium (Th), lead (Pb), and the lanthanides are key elements in geochemistry and cosmochemistry. Abundance ratios and isotopic ratios of these elements in rocks, meteorites, and airborne dust are used for estimating their origin, 1-3 dating of mineral formation, 4 history of mineralization, 58 and age determination of nuclear materials. 9-11
