“…These thermodynamic data also submit that all the extraction processes are determined by entropy terms, which is the characteristic of hydrophobic interaction. That indicates it is the main driving force for the removal of BPA by DESs from aqueous solution 64–67 …”

“…That indicates it is the main driving force for the removal of BPA by DESs from aqueous solution. [64][65][66][67] In this work, three ammonium-based DESs were prepared with mixing of tetra butyl ammonium bromide as the hydrogen bond acceptor (HBA) and glycerol, decanoic acid, oleic acid as the hydrogen bond donor (HBD). The densities and solution thermodynamic properties such as isobaric and excess isobaric expansivity, excess molar volume, partial molar volume, partial molar volume at infinite dilution, excess partial molar volume, apparent molar volume and apparent molar volume at infinite dilution were studied from 293.15 to 343.15 K at ambient pressure to understand the interaction between the aqueous bisphenol A and {[TBAB][Gly]}.…”

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.

“…The stoichiometry of extracting species is evaluated by slope analysis method (Shi et al 2017;Zhao et al 2018). As it can be observed, ionic liquids possess the better extracting characteristic especially in case of metal ion removal, when their alkyl chain is butyl or even longer to strengthen the hydrophobicity (Guezzen and Amine Didi 2016).…”

Pollution by toxic, non-degradable metals is a rising health concern in the context of increasing industrialization and metal demand. Diseases may include brain damage, cardiovascular problems, gastrointestinal disorders and cancer, calling for advanced methods to clean soil, water, wastewater and air. Here, we review the use of ionic liquids, which are considered as eco-friendly solvents, to remove metals. Ionic liquids have unique properties such as no vapor emission, good solvation ability, higher thermal stability and tunability. Ionic liquids separate efficiently metal ions from aqueous solutions by electrostatic, Van der Waals and ion-pair interactions. Ionic liquids can be recovered by stripping, then reused several times for liquid-liquid extraction, adsorption and membrane separation. Ionic liquids improve membrane stability in membrane separation, and they act as surfactant for adsorption.

“…Several studies have been developed to remove Hg(II) ions from aqueous solutions such as oxidation or chemical reduction methods [8], ion exchange, coagulation, electrochemistry, membrane adsorption [9][10] [11] [12], chemical coagulation [13], membrane filtration [14], and adsorption [4]. The adsorption method is one of the environmentally friendly methods and is relatively inexpensive.…”

The increasing pollution of toxic heavy metals in the environment is an important issue worldwide. Heavy metal ions such as mercury have attracted special attention because of their high toxicity and long half-life which increase the potential to accumulate in the food chain and cause serious damage to the environment. The potential of an adsorbent durian (Durio zibethinus) seed immobilized alginate bead was carried out and used for the adsorption of Mercury in an aqueous solution. Adsorbents were characterized by FTIR, SEM, and XRF. FTIR analysis shows the functional groups of alcohol, amine, and carboxylic acid. Scanning Electron Microscopy shows that the surface morphology of durian seed powder of granules and durian seed immobilized in Ca-alginate of like as tissue eggs in an egg box shape. XRF analysis durian seed immobilized showed that Hg(II) ion adsorbed as much as 37%. The adsorption parameter of Hg(II) ion are pH at 6 with an adsorption capacity was 1.553 mg/g, contact time at 150 minutes with adsorption capacity was 2.880 mg/g, mass 0.1 g with adsorption capacity of 2.274 mg/g, and concentration 250 mg/g with adsorption capacity of 62.067 mg/g.
