A multitechnique approach with theoretical insights has been employed to understand the complexation of trivalent lanthanides two β-diketones, viz. 1-phenyl-1,3-butanedione (L1) and 4,4,4-trifluoro-1-phenyl-1,3-butanedione (L2), in an ionic liquid (C6mim·NTf2). UV–vis spectral analysis using Nd3+ revealed predominance ML2+ ML4– species. The stability constants for PB complexes were higher (β2 ∼ 10.45 ± 0.05, β4 15.51 0.05) than those TPB 7.56 13.19 0.06). photoluminescence titration Eu3+...
Optimized complexes of Lu<sup>3+</sup>with TMDGA in 1 : 1, 2 and 3 stoichiometric ratios plots theoretically calculated stepwise binding energy.
A new universal scaling law relating the self-diffusivities of a binary fluid mixture and excess entropies its components is derived using mode coupling theory, reproducing empirical laws Dzugutov [Nature (London) 381, 137 (1996)] Hoyt et al. [Phys. Rev. Lett. 85, 594 (2000)] as special cases. The are tested through numerical calculations for Lennard-Jones mixtures wide range physical parameters, very good correlation observed. We have also arrived at relationship between cross-diffusivity...
Three benzene-centered tripodal diglycolamides (Bz-T-DGAs) were synthesized and evaluated for actinide, lanthanide, fission product ion extraction.
An amide functionalized multiwalled carbon nanotube (CNT-DHA) was used for efficient and selective solid phase separation of tetravalent (Th<sup>4+</sup>) hexavalent (UO<sub>2</sub><sup>2+</sup>) actinides.

Understanding the speciation of metal ions in heterogeneous hydrogen-bonded deep eutectic solvents (DES) has immense importance for their wide range applications green technology, environmental remediation, and nuclear industry. Unfortunately, fundamental nature interaction between DES actinide is almost completely unknown. In present work, we outline speciation, solvation mechanism, redox chemistry uranyl ion (UO22+) consisting choline chloride (ChCl) urea as hydrogen-bond donor....

The separation and utilization of radiotoxic 90Sr from liquid nuclear waste streams generated in the fuel reprocessing is highly desirable challenging. Herein, we studied dibenzo-18-cown-6 functionalized chloromethyl-polystyrene (CMPS-DB18C6) resin which displays an excellent affinity toward Sr2+ion adsorption aqueous solution. Adsorption behaviors were investigated as a function solution pH, contact time, concentration, temperature presence other metal ions. prepared grafted exhibits high...
The +5 state is an unusual oxidation of uranium due to its instability in the aqueous phase. However, it redox stable with PCs.
A new universal scaling law relating the self-diffusivities of components a binary fluid mixture to their excess entropies is derived using mode coupling theory. These laws yield numerical results, for hard sphere as well Lennard-Jones mixtures, in excellent agreement with simulation results even at low density region, where empirical Dzugutov [Nature (London) 381, 137 (1996)]] and Hoyt, Asta, Sadigh [Phys. Rev. Lett. 85, 594 (2001)]] fail completely. Kolmogorov-Sinai entropy also obtained.
Extraction of actinide (Pu4+, UO22+, Am3+) and lanthanide (Eu3+) ions was carried out using different diglycolamide (DGA) ligands with systematic increase in the alkyl chain length from n-pentyl to n-dodecyl. The results show a monotonous reduction metal ion extraction efficiency increasing this becomes even more prominent case branched (2-ethylhexyl) substituted DGA (T2EHDGA) for all studied. Steric hindrance provided by groups has strong influence controlling behavior DGAs. distribution...
