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

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
THE TRUEX PROCESS - A PROCESS FOR THE EXTRACTION OF THE TKANSURANIC ELEMENTS EROM NITRIC AC In WASTES UTILIZING MODIFIED PUREX SOLVENT*
TL;DR: A generic transurantc (TRU) element extraction/recovery process was developed based on the use of octyl(phenyl)-N,N-diiso-butylcarbamoylmetliylphosphine oxide, 0φD(iB)CMPO, dissolved in PUREX process solvent (tribntyl phosphate, TBP, in normal paraffluic hydrocarbon, NPH) as mentioned in this paper.
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
Srex: a newprocess for the extraction and recovery of strontium from acidic nuclear waste streams
TL;DR: In this paper, a new process for the extraction and recovery of strontium from acidic waste streams is described, called SREX (for Strontium Extraction), which extracts from acidic ( ≥ 1M HNO3) solution using a 0.20M solution of di-t-butylcyclohexano-18-crown-6 in 1-octanol.
