High-pressure ion chromatography (HPIC) was coupled with sector field inductively coupled plasma-mass spectrometry (SF-ICP-MS) to separate plutonium (Pu), uranium (U), neodymium (Nd) and gadolinium (Gd) nuclides from isobaric nuclides and to quantify them with high sensitivity. In this study, mixed bed ion exchange columns CG5A and CS5A were used, ...

Phosphors and optoelectronic thin film electronic device layers contain critical metals including lanthanides and indium that should be recycled. Solvent impregnated resins (SIRs) containing (i) DEHPA (ii) DODGAA and (iii) DODGAA with the ionic liquid [C4mim][Tf2N] are investigated in extraction chromatography methodologies to recover and separate ...

In this contribution we report the innovative use of metal-organic frameworks (MOFs), more specifically MIL-101(Cr), as a novel stable supporting material for rare earth adsorption from aqueous environment. The mesoporous MIL-101 was covalently functionalized with chelating carbamoylmethylphosphine oxide-type ligands (CMPO) via a three-step procedu...
In recent years, a great deal of interest has been focused on nitrogen-containing extractants for the separation of actinides from lanthanides. In this study, we synthesized a polyazamacrocycle-type C-8-cyclen ligand comprising four tertiary alkyl amino groups, for the extraction of Am3+ and Eu3+. The C-8-cyclen demonstrated a weak ability to extra...
The high sensitivity of AMS for actinides analysis can facilitate a range of studies aimed at improving understanding of how actinides behave in the environment. Former nuclear sites, which contain a range of levels of contamination with actinides, offer opportunities to study the migration and bioaccumulation of actinides. In addition to the evalu...
