Srivastava3,4, Arijit Sengupta3,4􀀍, Dipita Karmakar3,4, Sk. Musharaf Ali4,5, Willem Verboom6 & Prasanta K. Mohapatra3,4  \nIonic liquids have been emerged of as potential ‘green’ alternatives to the volatile organic compounds used in liquid-liquid biphasic extraction of metal ions. Their unique properties bring interesting chemistry during extraction of metal ions with respect to tuning the extraction mechanism, speciation, kinetics and energetics associated to it. Diglycolamide based ligands exhibited high selectivity towards the trivalent f cations due to their aggregation behaviour in the diluents. In view of this, it is imperative to understand the complexation of trivalent f cations into ionic liquid with tetra secondary butyl diglycolamide (TsBDGA). TsBDGA was found to form 1:1, 1:2 and 1:3 species predominantly with trivalent f cations. However, the complexation constant values for Nd3+ were found to be lower than those of the Eu3+ ion, as ascribed to lanthanide contraction. The complexation was found to be spontaneous in nature. On complexation, the local asymmetry around Eu3+ was found to increase and the diffusion coefficient values were reduced. The complexation was also indicated by shifts in the carbonyl stretching frequency in the FTIR spectra. Computation analyses were performed to optimize the energy, bond length and 3D structures of the Nd3+ as well as Eu3+ complexes in gas phase and solution phase alongwith the calculation of the Mulliken Partial atomic charge.  \nKeywords TSBDGA, UV-vis spectroscopy, Photoluminescence, DFT, Cyclic voltammetry  \nPartitioning of actinides is one of the proposed strategies for reduction in long term surveillance of highly radiotoxic waste generated from the back end of the nuclear fuel cycle1–3. The first step of the Plutonium Uranium Reduction EXtraction (PUREX) process is the co-extraction of hexavalent uranium and tetravalent plutonium by 30% tri-n-butyl phosphate (TBP) in n-dodecane. The organic phase containing U and Pu are subjected to change in oxidation state of plutonium from + 4 to + 3 to achieve the mutual separation from hexavalent uranium. The initial raffinate contained all the minor actinides, lanthanides, activation and fission products. In order to avoid long term surveillance, the partitioning and transmutation strategy has been followed. In actinide partitioning, the trivalent lanthanides and actinides were co-extracted into the organic phase resulting their separation from the rest of the other metal ions. In the text this was referred as the first step for actinide partitioning. In the subsequent step, the trivalent actinide and lanthanides which were separated from rest of the other metal ions were subjected for their mutual separation i.e. separation between trivalent lanthanides and actinides. Due to the complex nature of the matrices, presence of different metal ions and associated high radiotoxicity, efficient and selective separation plays key role in order to have desired performance of the nuclear fuel cycle. The first step of the partitioning pertains to the co-extraction of the trivalent lanthanides and actinides from aqueous acidic streams due to their similar chemical behaviour4–6; while the second step pertains to the mutual separation of them7–9. Different partitioning agents have been under consideration for the co-extraction  \n1UM-DAE Centre for Excellence in Basic Sciences, Mumbai 400098, India. 2Health Physics Division, Bhabha Atomic Research Centre, Mumbai 400094, India. 3Radiochemistry Division, Bhabha Atomic Research Centre, Mumbai  \n400 085, India. 4Homi Bhabha National Institute, Mumbai 400094, India. 5Chemical Engineering Division, Bhabha Atomic Research Centre, Mumbai 4000","cbCaicAzVIekPMNw","https://ap.wps.com/l/cbCaicAzVIekPMNw","pdf",4085957,16,"English","# Complexation study using TSBDGA\n## Extraction context and ionic liquids\n## Species formation and binding trends\n## Thermodynamics, structural changes, and spectroscopy\n## Computational modeling and charge analysis\n## Actinide partitioning background","[{\"question\":\"What species ratios does TSBDGA form with trivalent f cations?\",\"answer\":\"TSBDGA was found to form 1:1, 1:2, and 1:3 species predominantly with trivalent f cations.\"},{\"question\":\"Why are complexation constants for Nd3+ lower than for Eu3+?\",\"answer\":\"The complexation constants for Nd3+ are lower than those for Eu3+ ascribed to lanthanide contraction.\"},{\"question\":\"How is complexation experimentally indicated in the study?\",\"answer\":\"Complexation is indicated by shifts in the carbonyl stretching frequency in the FTIR spectra, along with changes such as increased local asymmetry and reduced diffusion coefficients.\"}]","Experimental and theoretical insight into the complexation of tetra secondary butyl diglycolamide (TSBDGA) with trivalent f cations into ionic liquid | PDF",1790733097]
