“…The calculated values of density data are in good agreement with the literature values. The literature and experimental density data for deionized water, DES 1 , DES 2 , DES 3 , and DES 4 were the least in error as deviation calculated by the absolute average relative deviation in percentage (AARD%), as shown in Table . − AARD % = ( 100 n ) ∑ I = 1 n ( | ρ experimental − ρ literature | ρ literature ) Here, ρ experimental and ρ literature are the density values from the experiment and literature, respectively, and n is the number of data points for comparison.

Volumetric Investigation of Cu(II) And Hg(II) Aqueous Mixtures with {Tetrabutylammonium Bromide + Glycerol (1:3)} Deep Eutectic Solvents and Extraction Performances of {Tetrabutylammonium Bromide + Capric Acid/Oleic Acid} over Divalent (Cu and Hg) Heavy Metals

In this study, density was measured for hydrophilic deep eutectic solvents based on tetrabutylammonium bromide (as hydrogen bond acceptor) and glycerol (as hydrogen bond donor) in a 1:3 mol ratio with an aqueous heavy metal (Cu/Hg) solution at various concentrations in the temperature range of 298.15− 348.15 K at atmospheric pressure. The excess molar volume, partial molar volume, excess partial molar volume, apparent molar volume, excess partial molar volume at infinite dilution, and isobaric expansivity were calculated to study the nonideal behavior of these pseudobinary systems. The obtained excess molar volumes (V m E ) of 72 systems were then fitted to Redlich−Kister-type polynomial expressions. In addition, the performance of the predictive conductor-like screening model for real solvents (COSMO-RS) model is capable of quantitatively observing the sigma surface, sigma profile, and sigma potential of the individual chemical species and six prepared deep eutectic solvents. The existence of bands was analyzed for hydrogen bond acceptors (HBAs), hydrogen bond donors (HBDs), and used metal salts using Fourier transform infrared (FTIR) spectroscopy. Hydrophobic deep eutectic solvents (DESs) removed heavy metal (HM) ions from the synthetic contaminated water stream. At lower concentrations of Hg 2+ ions, extraction efficiency showed a higher value of 98.85% with capric acid-based DESs. Similarly, the extraction efficiency for Cu 2+ ions reached a maximum of 54.25% in this study. Before and after extraction, the concentrations of divalent copper and mercury were analyzed using inductively coupled plasma optical emission spectroscopy (ICP-OES).

The structural features of water-ethanol, water-urea and water-ethanol-urea systems were studied on the basis of experimental estimates of kinematic viscosity at different temperatures and concentra-tions. For this purpose, the concentration dependences of the Gibbs energy of activation of the viscous flow, the enthalpy of activation of the viscous flow and the entropy of activation of the viscous flow of the studied systems were analyzed. The results show that ethanol has a structuring and then de-structive effect on water up to a concentration of 0.15 molar, and urea has a destructive effect on the structure of water, starting from such small concentrations. The addition of urea to the ethanol-water system does not affect the inversion point.

Flory's Statistical Theory (FST) has been applied to investigate excess thermodynamical parameters viz., excess enthalpy, excess entropy, and excess Gibbs free energy for eight binary mixtures of ionic liquids and water at different concentration and temperatures. The concentration and temperature dependent variations of excess enthalpy suggest that ionic liquid mixtures exhibit an endothermic nature and the presence of weak dispersive forces among their constituents. The positive excess Gibbs free energy of mixing points out that the pure components do not mix thoroughly for the systems under study. Overall, these binary systems are thermodynamically unfavorable suggesting that the mixing of ionic liquids and water is not energetically favored or spontaneous. Experimental molar volumes are compared with those calculated using FST and these values show excellent agreement. It affirms the validity of FST's application to these systems. Additionally, some partial properties have also been determined to explore the solute‐solvent interactions. The Redlich‐Kister (R‐K) polynomial model has been applied to excess thermodynamical parameters The high R2 values and low standard deviation values confirm the validity of fitting the RK polynomial model to the functions obtained using FST of liquids for these systems within the given temperature range.
