Lanthanides Release and Partitioning in Municipal Wastewater Effluents

Toxics, 2022
The use of lanthanides is increasing in our society, whether in communication technologies, transportation, electronics or medical imaging. Some lanthanides enter urban wastewater and flow through municipal wastewater treatment plants (WWTPs).

Influence of diluent alkyl substitution on the extraction of Am(III) and Eu(III) by a 6,6’-bis(1,2,4-triazin-3-yl)-2,2’-bipyridine ligand dissolved in alkylated cyclohexanone Diluents [PDF]

, 2012
Several alkylated cyclohexanones were investigated as potential diluents for the selective extraction of Am(III) from Eu(III) from nitric acid solutions by the CyMe4-BTBP ligand.

A summary of the variations in relative abundance of the lanthanides and yttrium in allanites and epidotes [PDF]

Bulletin of the Geological Society of Finland, 1985
Recalculation of 506 analyses of allanites and 53 analyses of epidotes has confirmed that these minerals preferentially concentrate the light lanthanides, but that the relative concentrations vary considerably with variation of the host rocks, with ...

Lanthanide contraction in linear lanthanide–oxygen clusters

Journal of Coordination Chemistry, 2014
Five coordination polymers containing linear lanthanide–oxygen clusters 1–5 have been synthesized by a hydrothermal reaction of 3-(quinolin-8-yloxy) phthalic acid (H2L) with the respective lanthanide salt. The X-ray single crystal structural analyses revealed that these five crystalline materials belong to two isostructures with formulas [LnHL2(H2O)2]n

Voltammetry in Determination of Trace Amounts of Lanthanides—A Review

Molecules, 2023
This paper presents an overview of approaches proposed in the scientific literature for the voltammetric determination of rare earth elements (mainly cerium and europium individually, as well as various lanthanides simultaneously) in manifold kinds of ...

Complexation of lanthanides, actinides and transition metal cations with a 6-(1,2,4-triazin-3-yl)-2,2’:6’,2’’-terpyridine ligand: implications for actinide(III) /lanthanide(III) partitioning [PDF]

, 2012
The quadridentate N-heterocyclic ligand 6-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-1,2,4-benzotriazin-3-yl)-2,2’:6’,2’’-terpyridine (CyMe4-hemi-BTBP) has been synthesized and its interactions with Am(III), U(VI), Ln(III) and some transition metal cations ...

Lanthanide Luminescence in Visible-Light-Promoted Photochemical Reactions

Molecules, 2020
The excitation of lanthanides with visible light to promote photochemical reactions has garnered interest in recent years. Lanthanides serve as initiators for photochemical reactions because they exhibit visible-light-promoted 4f→5d transitions that lead
