Conformational interconversion as a marker of third phase formation in the extraction of metal nitrates using tri-alkyl phosphate extractants in dodecane diluent: Insights from infrared spectroscopy
The changes observed on the conformational landscape of tri-alkyl phosphates due to its complexation with metal-nitrates and the influence of polarity of the surrounding environment has been interpreted. Observations from extraction studies involving model phosphates with nitrates of U(VI), Th(IV) and Pu(IV) have been utilized to extrapolate to liquid phase from the insights gained through the matrix isolation infrared and computational studies reported earlier on the conformations of phosphates in gas phase. An observable enrichment of ‘Trans’ form of free extractants while loading metal-nitrates into the organic phase is established as a premonition to phase splitting resulting in third-phase formation.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
