Separation of uranium(VI) and americium(III) by Extraction from Na2CO3–H2O2 solutions using methyltrioctylammonium carbonate in toluene
ABSTRACT Liquid–liquid extraction of carbonate and mixed peroxo-carbonate compounds of U(VI) and Am(III) from Na2CO3 aqueous solutions by methyltrioctylammonium carbonate in toluene has been studied. The main patterns of effect of extractant, Na2CO3, and H2O2 concentration on distribution and separation of U(VI) and Am(III) have been established. Using slope analysis and UV–vis spectroscopy, the compositions of U(VI) and Am(III) extractable compounds are established as (R4N)4[UO2(CO3)3], (R4N)4[UO2(О2)(CO3)2], and (R4N)6[(UO2)2(O2)(CO3)4] for U(VI); R4N[Am(CO3)2] and (R4N)3[Am(CO3)3] for Am(III), where R4N is the quaternary ammonium cation. The obtained data showed high efficiency of the studied carbonate system for extraction of U(VI) and its purification from Am(III). The maximum separation factor of U(VI) and Am(III) was 25.
期刊介绍：
Solvent Extraction and Ion Exchange is an international journal that publishes original research papers, reviews, and notes that address all aspects of solvent extraction, ion exchange, and closely related methods involving, for example, liquid membranes, extraction chromatography, supercritical fluids, ionic liquids, microfluidics, and adsorption. We welcome submissions that look at: The underlying principles in solvent extraction and ion exchange; Solvent extraction and ion exchange process development; New materials or reagents, their syntheses and properties; Computational methods of molecular design and simulation; Advances in equipment, fluid dynamics, and engineering; Interfacial phenomena, kinetics, and coalescence; Spectroscopic and diffraction analysis of structure and dynamics; Host-guest chemistry, ion receptors, and molecular recognition.
