Facilitated extraction membrane processes present a promising technology to replace conventional methods of producing and purifying glycerol. They offer green, ecofriendly, and sustainable platforms with economic benefits. Therefore, in this article, we are interested in improvements to current glycerol purification techniques, in particular, the development of a more efficient, cost-effective, and sustainable glycerol purification process. The current work presents studies relating to the use of three polymer inclusion membranes (PIMs) constituted by poly(vinyl alcohol) (PVA) as a polymer support and the extractive agents resorcinarene C-undecylcalix (4) (Res), dibenzo-18-crown-6 (Crw), and β-cyclodextrin (β-CD). The developed membranes are adapted to facilitate the extraction of glycerol using a separation technique based on the principle of membrane oriented membrane processes. Kinetic and thermodynamic models based on the interaction between the glycerol substrate and the extractive agent immobilized in the membrane phase were adopted for the determination of macroscopic, microscopic, and activation parameters. The computational approach based on the threedimensional representation of the molecules allowed us to elucidate the mechanism with probable interactions the movement nature of glycerol molecules and to explain the experimental values. All results showed that the Res extractive agent is more efficient than its agent counterparts Crw and β-CD, with apparent diffusion coefficient values (10 5 D*) of 18.03, 2.99, and 1.65 cm 2 •s −1 respectively at 308 K. The membranes adopted and tested for the extraction oriented processes of the glycerol compound from an algae extract show a high performance for the PVA/β-CD membrane with a purity of 98.4%, whereas for glycerol extracted through the PVA/Crw and PVA/Res membranes these purities are 85.2% and 78.8%, respectively. The results described for the quantification of oriented processes relating to the facilitated extraction of the glycerol compound are unpublished in the literature and present original studies necessary to develop and optimize a clean and sustainable technique for obtaining pure glycerol.

Background Paracetamol compound remains the most used pharmaceutical as an analgesic and antipyretic for pain and fever, often identified in aquatic environments. The elimination of this compound from wastewater is one of the critical operations carried out by advanced industries. Our work objective was to assess studies based on membrane processes by using two membranes, polymer inclusion membrane and grafted polymer membrane containing gluconic acid as an extractive agent for extracting and recovering paracetamol compound from aqueous solutions. Result The elaborated membrane characterizations were assessed using Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Kinetic and thermodynamic models have been applied to determine the values of macroscopic (P and J0), microscopic (D* and Kass), activation and thermodynamic parameters (Ea, ΔH#, ΔS#, ΔH#diss, and ΔH#th). All results showed that the PVA–GA was more performant than its counterpart GPM–GA, with apparent diffusion coefficient values (107D*) of 41.807 and 31.211 cm2 s−1 respectively, at T = 308 K. In addition, the extraction process for these membranes was more efficient at pH = 1. The relatively low values of activation energy (Ea), activation association enthalpy (ΔH≠ass), and activation dissociation enthalpy (ΔH≠diss) have indicated a kinetic control for the oriented processes studied across the adopted membranes much more than the energetic counterpart. Conclusion The results presented for the quantification of oriented membrane process ensured clean, sustainable, and environmentally friendly methods for the extraction and recovery of paracetamol molecule as a high-value substance.

“…The formation of a "substrate-extractive agent," the stabilities of which depend on the structure of the compounds and the nature of interaction sites, was observed. On the other hand, a jumping mechanism [61,62], in which the substrate moves while binding successively to several fixed carriers (considered as a complexation site), similar to the case of an ion-exchange membrane, was studied. Reversible association-dissociation reactions leading to the formation and decomposition of an unstable "host-guest" complex were carried out.…”

Background: Paracetamol compound remains the most used pharmaceutical as an analgesic and antipyretic for pain and fever. It has been detected in aquatic environments. The recovery of this compound from wastewater is one of the important operations carried out by modern industries. Its recovery is especially important for environmental protection. Currently, research is focused on membrane technology that has gained considerable interest over the last decades due to the various advantages that it presents.Result: Our work reports the selective extraction of paracetamol from liquid solution using two types of affinity polymer membranes: (i) polymer inclusion membrane (PIM) and (ii) grafted polymer membrane (GPM). The same extractive agent, gluconic acid (GA), is used for both. After total characterization, the developed membranes were adopted. Kinetic and thermodynamic models have been used to determine the values of various macroscopic parameters, permeability (P), and initial flux (J0), to understand the membrane performance. The same techniques have been used to determine the values of different microscopic parameters, association constant (Kass), and apparent diffusion coefficient (D*) that determine the interaction between the paracetamol substrates and the extractive agent, necessary for the diffusion of paracetamol molecules through the membrane. Similarly, the effects of initial concentration (C0), acidity (pH), and temperature were examined.Conclusion: The experimental results allow the determination of values of activation and thermodynamic parameters (Ea, ΔH#, ΔS#, ΔH#dis, and ΔH#th). The results explain the membrane performances and confirm that the energetic or kinetic aspects control the mechanisms related to the oriented processes. The results also indicate that it is possible to recycle wastewater and eliminate contaminants such as paracetamol.
