Use of Inductively Coupled Plasma Atomic Emission Spectrometer for Determining Metal Ion Uptake by New Extraction Chromatography or Ion Exchange Resins
EMSL Project ID
26199
Abstract
Extraction chromatography resins have been made for two classes of ligands that have high affinity for actinide ions: bicyclic diamides and Kläui ligands. Batch equilibrium sorption behavior for the actinide ions has been explored using radioactive tracers. However, the behavior of potential competing ions such as the lanthanides and iron(III) are of great interest with respect to the practical utility of the bicyclic diamides and Kläui ligands in actinide separations. In this project, we will use the analytical capabilities in the EMSL to determine the solution concentrations of selected non-radioactive elements both before and after contacting with the bicyclic diamide or Kläui ligand resins; other ion exchange materials may also be included for comparison. This will provide a quantitative measurement of the affinity of these materials for the metal ions investigated. The measurements will be made for Fe(III) and Ln(III) ions (Ln = metals in the lanthanide series).
