“…It implies that the density of component increases with increase in the steric hindrance and alkyl chain length of the DESs. The consistency of the equipment and procedures were verified by comparing the values with the experimental values reported by other literature 31,42 (Table 2). The density data of the individual components were fitted with least‐squares linear equations and regression coefficients (R 2 ) were calculated.…”

“…The densities of the pure components and the binary mixtures decreases with an increase in the temperatures due to the decrease of intermolecular interaction of molecules at higher temperature and increase of kinetic energy of the molecules. 41 It can be noted from Table 2 31,42 (Table 2). The density data of the individual components were fitted with least-squares linear equations and regression coefficients (R 2 ) were calculated.…”

Densities of pure distilled water, tetra butyl ammonium bromide glycerol{[TBAB][Gly]}, and different concentration of aqueous bisphenol A (aq. BPA) (i.e., 25, 50, 75, and 100 ppm) were measured at different temperatures from 293.15–343.15 K. Further, densities of the pseudo binary mixtures of aq. BPA and {[TBAB][Gly]} over the entire mole fraction were measured at different temperatures from 293.15–343.15 K. From these measured density data, the solution thermodynamic properties of the pseudo binary mixtures of aq. BPA and {[TBAB][Gly]} were calculated, and the excess molar volume data were correlated using the Redlich–Kister polynomial equation. Furthermore, the σ‐profiles and σ‐potentials of all the studied species were generated and analyzied in terms of H‐bond donor and/or acceptor at atom and molecular levels. Finally, based on the results of aq. BPA with {[TBAB][Gly]}, tetra butyl ammonium bromide decanoic acid {[TBAB][DA]} and tetra butyl ammonium bromide oleic acid {[TBAB][OA]} based deep eutectic solvents were used for the removal of BPA from the aqueous stream at 298.15 K and 1 atm. This process was characterized in terms of distribution coefficient (D), extraction efficiency (η), and also thermodynamic feasibility of the process at different temperatures.

BACKGROUNDTo improve the quality of wastewater and thereby to meet the standards as per environmental production agency in US and UK. In the present work, Malachite green (MG) and Naphthol Green B (NGB) has been taken as model dyes in wastewater. Solvent extraction process was carried out using deep eutectic solvents (DESs) as an alternative solvent for organic and ionic liquids.RESULTSThe possible molecular interaction between DESs and selective dyes in water were analyzed and discussed in details using volumetric properties including excess molar volume , partial molar volume , excess partial molar volume , apparent molar volume , isobaric thermal expansion () and excess isobaric thermal expansion (αE). Further, the extraction of selective dyes was conducted and characterized in terms of extraction efficiency (η), effect of temperature on extraction efficiency, effect of shaking time on extraction efficiency, effect of concentration on extraction efficiency, effect of HBD on extraction efficiency, distribution coefficient (D). Finally, the thermodynamic extraction feasibility was analysed by means of Gibbs free energy , change in enthalpy , and change in entropy .CONCLUSIONThere is possible molecular interaction between hydrophilic DESs and NGB/MG in water at molecular level. 96% of extraction efficiency was obtained for NGB using hydrophobic DESs like {[TBAB][DA]} and {[TBAB][OA]} whereas {[TBAB][DA]} and {[TBAB][OA]} gave above 72% removal efficiency of MG. Finally the thermodynamic feasibility of extraction process was analyzed and discussed. © 2023 Society of Chemical Industry (SCI).
