Journal ArticleDOI
A novel strontium-selective extraction chromatographic resin*
TL;DR: In this paper, the effect of nitric acid concentration on the selectivity of a novel extraction chromatographic resin consisting of an octanol solution of 4,4′(5′)-bis(t-butyl-cyclohexano)-18-crown-6 sorbed on an inert polymeric support for strontium over a number of alkali, alkaline earth, and other metal cations was evaluated.
Journal ArticleDOI
Separation and preconcentration of uranium from acidic media by extraction chromatography
E. Philip Horwitz,Mark L. Dietz,Renato Chiarizia,Herbert Diamond,Alice M. Essling,Donald G. Graczyk +5 more
TL;DR: In this paper, the effect of macro levels of selected elements on the sorption of actinide ions by a novel extraction chromatographic resin comprised of a solution of octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide in tri-n-butyl phosphate supported on an inert polymeric substrate is described.
Journal ArticleDOI
Separation and preconcentration of actinides by extraction chromatography using a supported liquid anion exchanger: Application to the characterization of high-level nuclear waste solutions
E. Philip Horwitz,Mark L. Dietz,Renato Chiarizia,Herbert Diamond,Sherrod L. Maxwell,Matthew R. Nelson +5 more
TL;DR: In this paper, a quaternary amine-based liquid anion exchanger was used for the extraction of actinides from nitric and hydrochloric acids, which exhibited preferential retention of tetravalent actinide over a wide range of acidities.
Journal ArticleDOI
Ionic Liquids as Extraction Solvents: Where do We Stand?
TL;DR: The unique physicochemical properties of ionic liquids (ILs) and the relative ease with which these properties can be fine-tuned by altering the cationic or anionic moieties comprising the IL have led to intense interest in their use as alternatives to conventional organic solvents in a wide range of synthetic, catalytic, and electrochemical applications.
Journal ArticleDOI
Ion-exchange as a mode of cation transfer into room-temperature ionic liquids containing crown ethers: implications for the ‘greenness’ of ionic liquids as diluents in liquid–liquid extraction
Mark L. Dietz,Julie A. Dzielawa +1 more
TL;DR: The transfer of strontium ion from acidic nitrate media into a series of 1-alkyl-3-methylimidazolium-based room-temperature ionic liquids containing dicyclohexano-18-crown-6 is shown to proceed via cation-exchange, in contrast to conventional solvents such as alkan-1-ols.
