Fluorinated calixpyrroles: anion-binding extractants that reduce the Hofmeister bias.
TLDR
Beta-octafluoro-meso-octamethylcalix and beta-decafluorosoro- meso-decamethylCalix were found to extract caesium salts of smaller anions as effectively as that of iodide into nitrobenzene (NB) thereby overcoming the Hofmeister bias normally observed for processes of this type. Expand
Spectroscopic monitoring of spent nuclear fuel reprocessing streams: an evaluation of spent fuel solutions via Raman, visible, and near-infrared spectroscopy
Abstract The potential of using optical spectroscopic techniques, such as Raman and visible/near infrared (Vis/NIR), for on-line process control and special nuclear materials accountabilityExpand
A Surprising Host−Guest Relationship between 1,2-Dichloroethane and the Cesium Complex of Tetrabenzo-24-crown-8
The structure of the complex [Cs(tetrabenzo-24-crown-8)(1,2-dichloroethane)2](NO3)·H2O was shown by X-ray crystallography to involve an unprecedented bidentate coordination of two 1,2-dichloroethaneExpand
Prediction of the carrier-mediated cation flux through polymer inclusion membranes via fundamental thermodynamic quantities: complexation study of bis(dodecyloxy)calix[4]arene-crown-6 with alkali
In a systematic study of alkali metal cation transport through a polymer inclusion membrane (PIM) with calixcrown carriers, a model that postulates diffusion-limited flux successfully describesExpand
Anion partitioning and ion-pairing behavior of anions in the extraction of cesium salts by 4,5' '-Bis(tert-octylbenzo)dibenzo-24-crown-8 in 1,2-dichloroethane.
TLDR
Observed anion extraction selectivity in this system, which may be ascribed predominantly to solvent-induced Hofmeister bias selectivity toward large charge-diffuse anions, was nearly the same whether cesium salts were extracted as dissociated ions or ion pairs. Expand
Investigations Into the Nature of Alkaline Soluble, Non-Pertechnetate Technetium
This report summarizes work accomplished in fiscal year (FY) 2013, exploring the chemistry of a low-valence technetium(I) species, [Tc(CO)3(H2O)3]+, a compound of interest due to its implication inExpand
Lipophilic ternary complexes in liquid–liquid extraction of trivalent lanthanides
The formation of ternary complexes between lanthanide ions [Nd(III) or Eu(III)], octyl(phenyl)-N,N-diisobutyl-carbamoylmethylphosphine oxide (CMPO), and bis-(2-ethylhexyl)phosphoric acid (HDEHP) wasExpand
Direct Spectrophotometric Analysis of Cr(VI) Using a Liquid Waveguide Capillary Cell
Hexavalent chromium Cr(VI) is a notorious ground water contaminant toxic to humans and animals. Assessment of an exposure risk for aquatic receptors necessitates frequent Cr(VI) concentration dataExpand
Technetium and Iodine Getters to Improve Cast Stone Performance
To determine the effectiveness of the various getter materials prior to their solidification in Cast Stone, a series of batch sorption experiments was performed at Pacific Northwest NationalExpand
