phase behaviour for aqueous two phase systems containing the ionic liquid 1 butylpyridinium tetrafluoroborate 1 butyl 4 methylpyridinium tetrafluoroborate and organic salts Sodium Tartrate ammonium citrate triSodium citrate at different temperatures
The Journal of Chemical Thermodynamics, 2013Co-Authors: Yuliang Li, Mengshi Zhang, Hang SuAbstract:Abstract The binodal curves of 1-butylpyridinium tetrafluoroborate + Sodium Tartrate at T = (298.15, 308.15 and 328.15) K and 1-butyl-4-methylpyridinium tetrafluoroborate + Sodium Tartrate/ammonium citrate/triSodium citrate at T = 298.15 K were experimentally determined. Three empirical equations were used to correlate the binodal data. The tie-line data were successfully correlated using the Othmer–Tobias and Bancroft and two-parameter equations. Factors affecting the binodal curves, such as temperature and the nature of the ionic liquids, were also studied. The two-phase area expanded with a decrease in temperature, whereas the absolute value of the slope of the ties slightly decreased with an increase in temperature. With an increase in the alkyl chain length of the ionic liquids (ILs) in the investigated systems, the binodal curves shifted closer to the origin. Finally, the effective excluded volume (EEV) values obtained from the binodal model were determined, and the salting-out ability decreased in the following order: Na3C6H5O7 > Na2C4H4O6 > (NH4)3C6H5O7.

Thermochimica Acta, 2012Co-Authors: Yuliang Li, Liheng Yang, Xuewei Zhao, Weisheng GuanAbstract:Abstract Binodal curves of the aqueous N-ethylpyridinium tetrafluoroborate ([EPy]BF4) + triSodium citrate (Na3C6H5O7), [EPy]BF4 + ammonium citrate tribasic ((NH4)3C6H5O7), [EPy]BF4 + Sodium succinate (Na2C4H4O4) and [EPy]BF4 + Sodium Tartrate (Na2C4H4O6) systems have been determined experimentally at T = 298.15 K. The Merchuk equation and two other equations were used to correlate the binodal data. The effective excluded volume (EEV) values obtained from the binodal model for these four systems were determined. The Othmer–Tobias, Bancroft, two-parameter and Setschenow-type equations were used for the correlation of the tie-line data. The results show that good agreement was obtained with the experimental data with the two-parameter and the Setschenow-type equations.

photoactivity of an anodized biocompatible tinbsn alloy prepared in Sodium Tartrate hydrogen peroxide aqueous solution
Applied Surface Science, 2021Co-Authors: Naoya Masahashi, Yu Mori, Hiroaki Kurishima, Hiroyuki Inoue, T Mokudai, Satoshi Semboshi, M Hatakeyama, Eiji Itoi, Shuji HanadaAbstract:Abstract A bioactive TiNbSn alloy was anodized in an electrolyte of Sodium Tartrate containing hydrogen peroxide (H2O2). The photo-induced characteristics of the anodized alloy were explored by focusing on its crystallinity and electrochemical conditions. The electrolysis curve of the anodization exhibited a higher voltage in the TiNbSn substrate than in the pure Ti substrate. Highly crystallized porous rutile-structured TiO2 was formed on TiNbSn, whereas relatively low-crystallized glassy anatase-structured TiO2 was formed on Ti. The absorption spectra of the oxide, formed on TiNbSn, revealed a steep absorption decrease with increasing wavelength while an explicit transition was not observed for the oxide formed on Ti. The anodized TiNbSn alloy exhibited superior photoactivity and generated hydroxyl radicals under ultraviolet (UV) illumination. The photoactivity of the anodized TiNbSn was attributed to TiO2, which was highly crystallized by the application of a high voltage, thus suppressing the recombination of the photogenerated carriers.

Measurement and Modeling of Phase Equilibrium in Aqueous Two-Phase Systems: L35 + Sodium Citrate + Water, L35 Sodium Tartrate + Water, and L35 + Sodium Hydrogen Sulfite + Water at Different Temperatures
Journal of Chemical & Engineering Data, 2012Co-Authors: Luciano Sindra Virtuoso, Karla A. S. F. Vello, Aline A. De Oliveira, Cristina Mazzeu Junqueira, Anderson F. Mesquita, Nelson H. T. Lemes, Raquel Moreira Maduro De Carvalho, Maria Do Carmo Hespanhol Da Silva, Luis Henrique Mendes Da SilvaAbstract:Phase diagrams have been determined for aqueous two-phase systems containing (EO)11(PO)16(EO)11, notation L35 (50% EO), and Sodium citrate, Sodium Tartrate, or Sodium hydrogen sulfite at different temperatures. The influences of the temperature and anion on the behavior of these systems were also analyzed. The temperature effect on the position of the binodal curves for systems containing Sodium citrate and Tartrate was not relevant, indicating a small enthalpy contribution associated with the phase separation. However, an enthalpic contribution for the phase splitting of the systems formed by Sodium hydrogen sulfite was observed. The ability of these three salts to induce the formation of a biphasic system with L35 followed the order Sodium citrate > Sodium Tartrate > Sodium hydrogen sulfite. In this work, the nonrandom two-liquid (NRTL) model was used to obtain new interaction energy parameters. The results were analyzed using root-mean-square deviations between experimental and calculated data in equil...
