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
Reverse-micelle formation in the partitioning of trivalent F-element cations by biphasic systems containing a tetraalkyldiglycolamide.
TL;DR: The experimental findings suggest that the peculiar behavior of TODGA with respect to the extraction of trivalent lanthanide and actinide cations arises from the affinity of these metal cations for the preformed TODGA reverse-micelle tetramers.
Journal ArticleDOI
Mass Transfer Rate through Liquid Membranes: Interfacial Chemical Reactions and Diffusion as Simultaneous Permeability Controlling Factors
TL;DR: In this paper, the authors derived equations describing the permeability of a liquid membrane to metal cations taking into account aqueous diffusion, membrane diffusion, and interfacial chemical reactions as simultaneous permeability controlling factors.
