Turanov, Alexander N. published the artcileAdsorption of lanthanides and scandium ions by silica sol-gel material doped with novel bifunctional ionic liquid, trioctylmethylammonium 1-phenyl-3-methyl-4-benzoyl-5-onate, Computed Properties of 4551-69-3, the publication is Journal of Environmental Chemical Engineering (2016), 4(4_Part_A), 3788-3796, database is CAplus.

Sol-gel processed silica doped with a novel bifunctional ionic liquid, trioctylmethylammonium 1-phenyl-3-methyl-4-benzoylpyrazol-5-onate ([A336]⁺[L]^–), was prepared and used as a sorbent for recovery and separation of scandium and lanthanides from nitric acid solutions The effect of HNO₃ concentration in the aqueous phase on the adsorption of microquantities of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu is considered. A significant synergistic effect was observed for scandium and lanthanide adsorption from aqueous solutions Sc(III) is sorbed from aqueous solutions much better than lanthanides(III) and separation of Sc(III) from lanthanides(III) can be achieved by simple adjusting acidity of the aqueous phase. The efficiency of lanthanide(III) adsorption from low-concentration HNO₃ solutions increases with an increasing at. number The process of lanthanide(III) adsorption is exothermic, spontaneous and follows a pseudo-second-order kinetic model. The potentialities of the doped silica material for the preconcentration of lanthanides(III) and Sc(III) from nitrate solutions are demonstrated.

The resulting complexes were characterized from elemental anal., vanadium determination, molar conductance, magnetic measurements, thermogravimetric (TG) anal., IR, electronic mass, and ESR studies. The thermal decomposition processes of one representative complex is discussed, and the order of reaction (n) and the activation energies (E_a) were calculated from TG and differential TG curves. Mol. geometry optimizations, mol. surface electrostatic potentials, vibrational frequency calculations, bond lengths, bond angles and dihedral angles, and natural at. charges obtained by natural bond orbital and Mulliken population anal. and calculations of mol. energies, HOMO and LUMO were performed with the Gaussian 09 software package using d. functional theory methods with Becke3-Lee-Yang-Parr (B3LYP) hybrid exchange-correlation functional and the standard 6-311G() basis set for (ampph-glsH₂) and LANL2DZ basis set for one of its complexes, [VO(ampph-gls)(H₂O)]. No imaginary frequency was found in the optimized model compounds, and hence it ensures that the mol. is in the lowest point of the potential energy surface, i.e., an energy min. Finally calculated results were applied to simulate IR spectra which show good agreement with observed spectra. Based on exptl. and theor. data, suitable square pyramidal structures are proposed for these complexes.
